This short but meaningful verse is the answer to several questions that might be raised; saying: ``And in retaliation there is life for you! O, you men of understanding, so that you might avoid evil.'' This verse has now turned to an Islamic slogan commonly issued; signifying that Islamic retaliation has no ground for vengeance, Had the law of retaliation not been recommended, the cruel merciless, inhuman, would feel being safe and secure, and through their evil deeds would make a Hell of the social life; so much so that some countries wherein retaliation is abolished, the number of murders and crimes has abruptly increased.
