The Law of Equivalence
5:45 And we decreed for them in it that: the life for the life, the eye for the eye, the nose for the nose, the ear for the ear, the tooth for the tooth, and an equivalent injury for any injury. If one forfeits what is due to him as a charity, it will atone for his sins. Those who do not rule in accordance with GOD’s revelations are the unjust.

“Moreover, the tit-for-tat strategy has been of beneficial use to social psychologists and sociologists[who?] in studying effective techniques to reduce conflict. Research has indicated[who?] that when individuals who have been in competition for a period of time no longer trust one another, the most effective competition reverser is the use of the tit-for-tat strategy. Individuals commonly engage in behavioral assimilation, a process in which they tend to match their own behaviors to those displayed by cooperating or competing group members. If the tit-for-tat strategy begins with cooperation, then cooperation therefore ensues. On the other hand, if the other party competes, then the tit-for-tat strategy will lead the alternate party to compete as well. Ultimately, each action by the other member is countered with a matching response, competition with competition and cooperation with cooperation.
