THE QURAN CYCLE: Imitation or Cooperation?

In Islam, Quran, psychology on October 2, 2009 at 5:45 am

وَتَعاوَنوا عَلَى البِرِّ وَالتَّقوىٰ ۖ وَلا تَعاوَنوا عَلَى الإِثمِ وَالعُدوٰن

Translation: And cooperate in righteousness and piety, and do not cooperate in sinfulness and transgression

06 Shawwal, 1430:

Ramadaan ends. Qur’an – its recitation, its wisdom, and the learning from it – continues. I had begun the “Quran in Ramadaan”  series with the ambitious intent of sharing my inspirations from my reading of the Qur’an on a daily note basis. My high-flying dreams soon crashed back flat on earth what with the realities of PC problems, connection failures, and the intensely on-edge schedule of Ramadaan. Ultimately, I was able to manage barely 5 posts instead of my orignally imagined 29!

However, with the grace of God, the sane idea has entered my head that Qur’an is not really meant to be restricted to Ramadaan; nor is Ramadaan really meant as a once-in-a-year occasion for serious thinking and behaving. Our salat, our strivings, our zikhr, our practices of sunna, our recitation of the Qur’an everything continues beyond Ramadaan so why not this practice of sharing observations inspired by the Book.

I sincerely pray that Allah subhanahu wa ta’ala guides me well and helps me increase my own understandings and insights foremost through this exercise. I also depend on my readers’ feedback. I intend it as a cooperative learning venture.

Today’s Ayah

Today’s ayah is a segment from ayah no. 2 of Sura Al-Maida. It is in the context of warning Madina’s Muslims against unfair dealings with Mecca’s polytheists (mushrikeen) after the latter had stopped these Muslims from performing the Hajj of Ka’aba.

Our Creator lays down an overarching rule of cooperation, not just with non-Muslims; the rule is general and can be applied to any case of group interaction. The translation for bir is righteousness and is applicable to any form of good deeds. The word taqwa is a multi-faceted word and in different translations and tafaseer it is elaborated as “God-consciousness”, “protecting oneself from doing wrong” or “fear of incurring God’s wrath or punishment” The word “icm” refers to all forms of wrong and immoral acts and the word “udwaan” implies criminal violation of the rights of another individual, group or institution.

Very simply, our Creator here asks us to cooperate in good things, and not in bad things.  

Co-operating with the non-believers

This is one of the verses that clarifies the nature of permissible relations with the non-believers. There is a common myth that has been wrongfully popularized in the name of Islam by Muslims and non-Muslims alike that Islam encourages hatred, prejudice and violence towards non-believers. But that is not true as evidenced by this, and indeed, many other verses in the Qur’an.

Qur’an clearly distinguishes those non-believers who have actually transgressed against the believers, who plot and conspire against them and act out their conspiracies, in particular those who are directly responsible for wrongful group actions taken against muslims (re: a’immat-al-kufr, the archetypes of faithlessness, Sura Tauba 12) with those peaceful ones who are simply leading their lives according to their belief systems. These distinctions have been most plainly clarified in Sura Al-Mumtahina 8 & 9:

As for such [of the unbelievers] as do not fight against you on account of [your] faith, and neither drive you forth from your homelands, God does not forbid you to show them kindness and to behave towards them with full equity: for verily, God loves those who act equitably. (8). God only forbids you to turn in friendship towards such as fight against you because of [your] faith, and drive you forth from your homelands, or aid [others] in driving you forth: and as for those [from among you] who turn towards them in friendship, it is they, they who are truly wrongdoers! (9).

Forms of Cooperation

When it comes to actual cooperation, Qur’an only distinguishes in terms of the areas of cooperation. For here, we clearly see that this injunction is in direct reference to those Mushrikeen (polytheists) who fall on the criteria of antagonism laid out in the verse referenced above. They drove Muslims out of their homes, they had a history of plotting war and breaking pacts with Muslims, and they had stopped Muslims from performing an act of worship which was annualy performed by millions of pilgrims from all over Arabia.

So even with these enemy-minded people, Qur’an distinguishes and permits cooperation where it leads to the general good of mankind.

Cooperation with non-Muslims indeed exists at many levels in today’s world. But an obvious question enters our mind, that is: is the kind of cooperating taking place really the Qur’anic kind? More often than not, sadly, the answer is not. We do not just cooperate in the really goodly things. We cooperate primarily in wasteful, and mostly sinful activities in the name of culture. We cooperate in mass capitalism that makes it more and more difficult for the ordinary citizen to eke out an honest living. We cooperate through political alliances (and dalliances!) that ultimately serve against our own brethren. And, speaking of lifestyles, values, attitudes, and aims of life, we actually do not cooperate. We IMITATE. Let us differentiate between cooperation and imitation.

Cooperative Learning

[cross-reference here]

Cooperation refers to making a joint effort to accomplish common goals beneficial to oneself and to all parties concerned. In contrast with imitation learning, any cooperative learning effort involves a positive-minded interdependence, face-to-face promotive interaction, individual and group accountability, use of interpersonal and group skills, and group processing such as monitoring one’s own progress towards the goals, and maintaining effective working relationships.

Both experimental and correlational research on use of cooperative learning strategies (as reviewed by Johnson & Johnson, 1989) has shown that, in contrast to traditionally competitive and individualistic learning or work efforts, cooperative learning leads to i) higher achievement and greater productivity, ii) care, support and commitment in relationships, iii) and greater levels of psychological health, social competence, and self-esteem.

These effects can, of course, only be achieved if the true spirit of cooperative learning has been applied: equal effort by all parties involved, and the sole regard of communal benefit.

Imitation Learning

Imitation learning is a form of observational learning whereby an individual observes and retaisn the behavior of a model, and is motivated enough to reproduce it in one’s own life.

This concept was originally researched by Albert Bandura. His work reveals three principles involved in imitation learning (click here for cross-reference of the following):

1. The highest level of observational learning is achieved by first organizing and rehearsing the modeled behavior symbolically and then enacting it overtly. Coding modeled behavior into words, labels or images results in better retention than simply observing.

2. Individuals are more likely to adopt a modeled behavior if it results in outcomes they value.

3. Individuals are more likely to adopt a modeled behavior if the model is similar to the observer and has admired status and the behavior has functional value.

Bandura also  identified three basic models of observational learning (cross-reference of the following):

  1. A live model, which involves an actual individual demonstrating or acting out a behavior.
  2. A verbal instructional model, which involves descriptions and explanations of a behavior.
  3. A symbolic model, which involves real or fictional characters displaying behaviors in books, films, television programs, or online media.

The prevalent Muslim trend

An analysis of these points reveals what has happenned in Muslim nations which has ended in the mass cultural invasion that now continues. The majority of the blame lies on our own shoulders. Had we maintained or promoted the highly functional Muslim guidelines for societies in our respective families, neighborhoods and governments, we could have been adequate role models for our subsequent generations.

Through categorical, incomplete, and distorted application of Islamic guidelines, over the years a number of Muslim societies associated negative outcomes (torture, undue restrictions, superstitiousness, and impracticality) with otherwise universal and highly constructive principles. “Valued outcomes” seem to come more often from Western cultures in form of intellectual stimulation, skill development, technological advancement and comfortable lifestyles. On the other hand, history has witnessed these same outcomes as the hallmark of Muslim, rather than non-Muslim, societies.

Two things have further reinforced Western role-modelling in our generations’ conscious and subconscious mind:  Our education system and entertainment channells. The structure of the education system prevalent all over the globe is now Western. But that is not the main issue. The main issue is that we are mostly teaching Western content at all levels. This does not apply only to Cambridge or Oxford exam systems in our countries. All university level teaching relies on textbooks from the Western worlds. The same is now happenning in many of the private schools of Pakistan (Of relevance here is the infamous matter of Dawood public school in my city, Karachi).

The primary reason, of course, is the lack of genuine research and quality textbook writing on OUR part. However, even while teaching, it is possible to tailor concepts and research findings in the context of our values which teacher typically do not do. More criminal: few educationists (teachers and mangers) actually encourage the kind of sincere, purposeful, and truly scientific effort-making needed to replace the easy models with more indegenous ones. That is why our generations do not seem to adopt the more functional values apparent in Western societies; rather, in the name of progressiveness, we readily focus and copy only the very material, short-sighted and mostly sinful styles and values.

These effects are multiplied many times by the entertainment industry. Being open-minded is being equated with physicality in illegitimate relationships and blind acceptance of everything offered in the name of science and technology. Being achieving is equated with self-centered individualism that cuts the flow of positive human sentiment in society leading to more and more alienation, selfishness, disregard of others’ right and benefit, dishonesty and lack of quality in one’s own duties, and single-minded pursuit of concrete comforts stripped of the glow of interpersonal satisfaction.

It is clear that we cannot derive the intended benefits of cooperative learning unless the demands of this form of learning are fulfilled.

It is certain that we can NEVER obtain (neither deserve) the fruits of our Creator’s wisdom unless we are prepared and ready to study and incorporate our rich Islamic heritage and to transfer it to our developing generation.

May Allah guide us. Ameen

QURAN IN RAMADAAN: Perfect Attributions

In Quran, Ramadaan, psychology on September 19, 2009 at 4:43 am
ما أَصابَكَ مِن حَسَنَةٍ فَمِنَ اللَّهِ ۖ وَما أَصابَكَ مِن سَيِّئَةٍ فَمِن نَفسِكَ ۚ وَأَرسَلنٰكَ لِلنّاسِ رَسولًا ۚ وَكَفىٰ بِاللَّهِ شَهيدًا ﴿٧٩﴾ (79) Whatever good happens to thee is from God; and whatever evil befalls thee is from thyself. AND WE have sent thee [O Muhammad] as an apostle unto all mankind: and none can bear witness [thereto] as God does.
-
1430, 28 Ramadaan:
-
The above quoted is Ayah no. 79 from Sura Al-Nisa. It is taken from the portion of the text where in a series of verses, Allah subhanahu wa ta’ala exposes the true state of minds in Madina’s hypocrites and reveals and corrects their explanations of events.
-
These hypocrites, while acknowledging God as the source of happy events (reference: Al-Nisa, 78), used to blame the holy Prophet (salla Allahu alaihi wa sallam) on unhappy occurings such as death and injury in confrontations with the enemy.
-
People’s attempts to explain the causes for events and happennings have been referred to as ‘attributions’ in psychology. I will first describe the concept as explicated in psychology and then I will come back to the perfect attributional style that Allah teaches us here in conjunction with another verse in Quran quoted below.
-
Attributional Style
Attribution is a concept in social psychology. All of us attempt to explain our own behavior, other’s behaviors as well as circumstances and events occuring arround us. Where various psychologists have contributed various concepts and research findings, the one I’m focusing here is Weiner’s attribution theory.
-
Weiner’s dimensions of attributions
Weiner (1986) argued that people’s attributions can be characterized in terms of three dimensions (below, as originally adapted by Abrahamson, et al. 1978):
1. internality/externality
2. stability/unstability
3. globality/specificity
-
Internal explanations look for personal causes of positive or negative occurences: such as ability, effort, shortcomings, behavior, etc. External explanations look for causes outside oneself such as others, chance, fate, God. Stability refers to the fact that the proscribed cause is supposed to be permanent such as a ‘irrecovable handicap’, ‘being the decided victim of someone’s cruelty’, or ‘a permanent fixture for misfortune’. Instability means the assumed causes have a changeable nature; for instance a ‘transient lack of practice’, ‘a stroke of luck’, ‘an accidental mistake’. Global attributions are supposed to prevail across most of the situations of one’s life; for e.g. an ‘overarching lack of general intelligence’, ‘being a good person’, etc. Specificity implies causes that relate only to the particular situation or event being explained; such as ‘being good in maths’, ‘the trouble-giving interview panel’.
-
The Quranic concept of Attribution
Quran divides attributions into basically two types: Events resulting from our own actions (or lack of actions) and events resulting by the decree of God.
-
These attributions correspond with the choice vs fate distinction in Quranic thought. At the abstract level and in principle everything happens directly or indirectly as a result of God’s interventions (i.e., fate). These interventions could be in the form the laws of nature formulated by God upon which the whole universe (including the human world) is running. They could be in the form of what happens to us as a result of others’ actions. They could be in that rare form of miracles. They could be in the form of that general decree by God that whatever deliberate action (good or bad) we fix upon and attempt to engage in, angels have been pre-ordered to let it happen (as in authentic ahadith).
-
However, as part of this fate, we can also achieve specific ends on our own as specific outcomes: a phenomenon which has been discussed in Quran and hadith in terms of two related concepts: Ikhtiyar (choice) and Tadbeer (strategy). For these specific outcomes then we are responsible and the internal attribution is then valid. On the other hand, some negative occurences also happen as more indirect consequences of our own negative (bad or faulty) behaviors. These may be considered as Jaza-e-Dunya (retribution in the world) and here too internal attributions are valid.
In all other cases, only external attribution (that is, those referred to God’s decree) are the best course as apparent when we consider the verses Al-Nisa 79, and Al-Hadeed 22 & 23 in conjunction; an idea that is supported in many other instances in our religious texts.
-
ما أَصابَ مِن مُصيبَةٍ فِى الأَرضِ وَلا فى أَنفُسِكُم إِلّا فى كِتٰبٍ مِن قَبلِ أَن نَبرَأَها ۚ إِنَّ ذٰلِكَ عَلَى اللَّهِ يَسيرٌ ﴿٢٢﴾ (22) NO CALAMITY can ever befall the earth, and neither your own selves, unless it be [laid down] in Our decree before We bring it into being: verily, all this is easy for God لِكَيلا تَأسَوا عَلىٰ ما فاتَكُم وَلا تَفرَحوا بِما ءاتىٰكُم ۗ وَاللَّهُ لا يُحِبُّ كُلَّ مُختالٍ فَخورٍ ﴿٢٣﴾ (23) [Know this,] so that you may not despair over whatever [good] has escaped you nor exult [unduly] over whatever [good] has come to you: for God does not love any of those who, out of self-conceit, act in a boastful manner –
-
For instance, many a times when something negative befalls us it is to be supposed as a test of our faith from God. This corresponds with the concept of “acceptance/resignation” as an effective coping strategy when all other attributions (blaming oneself, or someone else, or ‘chance’) will backfire (for an interesting explication of this concept, click on this Google Books link).
The same attribution holds when positive occurences take place. However, here there seems to be an apparent contrariness: what are we supposed to think when something negative happens? Is it a Jazaa or a Bala (test)?
After some ponderance, firm believers can easily resolve this issue in a manner that their readings of tafseer and hadith will validate:
-
The Perfect Attributions
  • All events that take place in one’s life or around one are by default from God.
  • Regardless of the nature of the occurence – positive or negative – , it is a test for our skills, attitudes and most importantly our faith.
  • In case of negative occurences there is cause for additional thought particularly when we can relate the happenning to a particular chain of events involving a series of actions on our part that fall under the head of Choice (Ikhtiyar) and Strategy (Tadbeer). When the link between our intentional and strategic choices with the subsequent outcomes is logical, we are to accpet the responsibility rather than just file it away under the head of Bala bis-Sayyi’ah (Test by a negative occurence).
  • In case of a positive occurence, there is a particular need to focus on the ‘blessidng’ side, no matter what the contribution of our own Choice and Strategy in it. This is in view of our essentially weak natures consistently accessible to satanic attitudes of arrogance, self-promotion, inflated self-esteem, and a foolish  superiority (which are always followed by belittling others by heart, tongue, or hand).  
 

 May Allah allow us to benefit from His perfect guidance.

QURAN IN RAMADAAN: Healthful Dispositions of Personality

In Quran, Ramadaan, psychology on September 17, 2009 at 4:19 am

19 Ramadaan, 1430:

الَّذينَ يُنفِقونَ فِى السَّرّاءِ وَالضَّرّاءِ وَالكٰظِمينَ الغَيظَ وَالعافينَ عَنِ النّاسِ ۗ وَاللَّهُ يُحِبُّ المُحسِنينَ ﴿١٣٤﴾

(134) Those who spend in prosperity and in adversity, for those who curb their anger and those who forgive people. And Allah loves the charitable

This is one of the oft-quoted verses of the Quran in Sura Al-i-Imran. In this ayah and the next, Allah Subhanahu Ta’ala describes the characteristics of those individuals for whom Paradise has been created; and there are two descriptors of this highlighted group used here and elsewhere: Muttaqeen (ayah 133) and Mohsineen (referred above). 

Three prominent characteristics have been selected here which share the common threads of mature self-control and a basic love and trust for people. Both psychological theory and individual and social psychological researches include these among the most healthful behaviors associated with the highest forms of mental functioning and optimal physical health. My wish here is to explore the psychological aspects of these traits.

Prosocial behavior, forgiveness, and anger control

Prosocial behavior may be defined as “caring about the welfare and rights of others, feeling concern and empathy for them, and acting in a way that benefits others” [wikipedia]. In Islam prosocial behavior is valid only if it is fueled by pure unselfish interest in others, here represented by one of it’s noblest forms: helping others monetarily.

Forgiveness occurs when we cease to be indignated or angry with someone perceived as having offended in some way. Legally, this involves taking back the criminal charges or forgiving punishment or restitution. Psychosocially, the forgiveness should be internal – from the heart – with restoration of normal relations if it were an acquaintance. It is often accompanied by ‘forgetting’ the past offensiveness of the transgressor.

Anger is that ”predominant feeling behaviorally, cognitively, and physiologically when a person makes the conscious choice to take action to immediately stop the threatening behavior of another outside force” (DiGiueseppe & Tafrate, 2006). This definition may be modified to count situations when we decide that the other has behaved unjustly towards us or some other object we love, although we may not necessarily plan to take action.

The three traits are inter-related. Forgiveness involves eliminating anger and the more we nurture anger in us the less prosocial we will be.

Self-actualizers and Fully-functioning individuals

 

Self-actualization is a concept that was popularized by Abraham Maslow’s theory of hierarchy of needs. Self-actualizers represent the epitome of psychological functioning and mental health and reach this high stage after having come to terms with all their lower level needs (such as basic needs for physical and emotional survival). Defining self-actualizing as “the desire for self-fulfillment”, “the desire to become more and more what one is, to become everything that one is capable of becoming” he identified several characteristics of self-actualizing individuals. Here is a list:

  • An accurate perception of reality. Healthy persons see the world as it is, rather than as distorted by their needs and beliefs. Maslow writes, “The neurotic is not emotionally sick; he is cognitively wrong.” Unhealthy persons fit the world to fit the shapes of their fear, needs, and values.

  • A general aceptance of nature, others, and oneself.
  • Acceptance of both one’s shortcomings and strengths, but without a lot of worry about them.
  • Spontaneity, simplicity, and naturalness. Not pretentious, display their emotions honestly. But are also thoughtful and considerate of others. Can play the required social games when necessary to avoid hurting someone’s feelings, but don’t do so otherwise.
  • A focus on problems outside themselves. Commitment to their work. Dedication to work, absorption in it, satisfaction from it.
  • A need for privacy and independence. Neurotics, by contrast, are usually highly emotionally dependent on others.
  • Autonomous functioning. Able to be relatively independent of their social and physical environments.
  • “Freshness of appreciation.” Ability to appreciate experiences as if they wwere new. They tend to continue to be greatful for what they possess and can experience.
  • Some self-actualizers have many peak experiences.
  • Social interest (Alfred Adler’s term.) Deep feelings of empathy and affection for all human being. Feeling of kinship with all people, even with other living beings.
  • Ability to maintain strong, rich relationships.
  • A democratic character structure. Self-actualizers are not authoritarian, do not want “power over” others or to be subjegated by others. Acceptance of all people regardless of class, education, ethnic differences, etc.. They don’t act superior toward anyone, but are ready wo learn from anyone. Distinguish clearly between means and ends, and also beween right and wrong. They have a clear sense of ethics, rather than being governed by expediency.
  • Have an unhostile sense of humor.
  • Creativeness. Original, inventive, and innovative in whatever their realm of life may be. Creativeness is more an attitude, an expression of psychological health, and is concerned with how we perceive and react to the world
  • Self-sufficiency and autonomy. Resistant to social pressures about how to think or act. Maintain an inner detachment, guided by themselves. But not rebellious for the sake of rebellion.
  • Apart from the secure self-reliant individuality, another prominent overarching trait evident here is a base of strong positive emotions for others in general. And it is this dimension of self-actualization, which operationally does encompass the specific emotional competencies we are discussing. 

     Carl Rogers gave a related concept of full-functioning individuals. He believes that “the core of man’s nature is essentially positive” (1961). Fully-functioning individuals represent mental health and maturity because they are open to new experiences, accept their weaknesses, trust themselves and others and are able to live authentically – that is, close to their truest basically good and creative natures. Rogers strongly believed that such kind of maturity can be achieved only in a psychologically healthy atmosphere of trust and dignity.

    In today’s culture of self-promotion, blind individualism, and exploitation, it is the noble traits of loving and forgiving others and going out of one’s way to bring a positive difference to others’ lives which can nurture such full-functioning responsible and mature citizens of the world.

    The above conclusions are indeed supported by decades of research in individual and social psychologies. I quote below some of the more recent research findings linking these traits with both psychosocial and physical health benefits.

    Prosocial behavior research

    Prosocial behavior leads to higher positive effect (Piliavin et al., 1981) and can relieve bad moods (Cialdini and Kenrick, 1976). People learn to associate such behavior to social rewards (Kenrick et al., 1979). Overtime, they are linking helping others to positive outcomes whether or not rewards were actually provided. It seems prosocial behavior can become internally rewarding. Prosocial behavior can convey a sense of personal control (Willigen, 1998) and is positively related to self-esteem (Yogev and Ronen, 1982), personal efficacy and confidence (Yates and Youniss, 1996).  Those who provide active support to their acquaintances have demonstrably higher longevity, even after taking into account other determiners of mortality rates such as demographic, personal and health characteristics (Brown et al., 2003). Brown et al. suggested that giving support enhances recovery of the cardiovascular system in negative emotions, thus affecting mortality. More socially isolated people benefit most from these effects of prosocial activity, suggesting that the effect is channelized through their increased social integration and interaction. Youth volunteers show lesser risk of drug intake, poor academic performance, or legal entanglements in later life (in Barling and Cooper, 2008  SAGE handbook of OB).

    Forgiveness research

    Lawler et al. (2004) found that both current and general levels of forgiveness were related to various health indicators including physical symptoms, medication usage, sleep quality, fatique and somatic complaints. These health benefits could be explained through spirituality, social skills, and reductions in negative affect and stress. Authors concluded that both current and general levels of forgiveness influenced health most strongly by lowering the degree of negative affects experienced.

    Positive effects of forgiveness can be explained through elimination of the hazards of unforgiveness. When we don’t forgive others we experience a horde of negative emotions such as resentment, bitterness, hatred, hostility, residual anger, and fear (Worthington et al., 2001). These emotions have strong potential to disturb both mental and physical health. Forgiveness replaces such negative affect with positive love-based emotions. Ultimately, the health effects are channelled through physiological changes.

    Forgiveness can modulate our mental health indirectly as well, through its effect on social support, interpersonal functioning, and health behaviors (Temoshok & Chandra, 2000; Worthington et al., 2001).

    Anger Control Research

    Anger is the root cause of many social problems such as crime, abuse, divorce, as well as myriad of physical and emotional health conditions. The physical and social health of the affected is itself disturbed (Graham-Bermann & Seng, 2005). A survey of around 6,ooo British families (Flouri, E., 2005) found that angry yound adults had more health problems and remained angry and dissatisfied with their life in their adulthood as well. Friedman (1991) had reported that hostile college age students had overweight, high blood pressure and high cholesterol problems, had smoked cigarettes and drank coffee and alcohol compared with the comparison group.

    On the other hand, controlling our angry feelings helps us in remaining healthy by engendering in us a sense of being in control. It encourages the positive love-based emotions of trust, acceptance, with a direct reduction in the negative and stress-causing appraisals that others are mean, selfish and exploitative (Tucker-Ladd, 2005). Instead of letting loose in anger, we learn healthier, assertive ways of expressing our negative emotions, increasing our satisfaction with self, life and the world.

    May Allah enable us to meaninfully benefit from his guidelines in the remaining Ramadaan and afterwards. Ameen
