The repayment of a bad action is one equivalent to it. But if someone pardons and puts things right, his reward is with Allah. Certainly He does not love wrongdoers. (Surat Ash-Shura, 40)
those who give in times of both ease and hardship, those who control their rage and pardon other people – Allah loves the good-doers – (Surat Al ‘Imran, 134)
But if someone is steadfast and forgives,that is the most resolute course to follow. (Surat Ash-Shura, 43)
Abu Hurayrah, may Allah be pleased with him, reported that a man said to the Prophet (saws), “Advise me.” He said, “Do not become angry.” The man repeated his request several times, and each time the Prophet (saws) told him, “Do not become angry.”(Reported by al-Bukhari, Fath al-Baaree, 10/456)
The Messenger of Allah (saws) said: “The strong man is not the one who can overpower others (in wrestling); rather, the strong man is the one who controls himself when he gets angry.” (Reported by Ahmad, 2/236; the hadeeth is agreed upon)
The righteous (al-muttaqoon) are those praised by Allah in the Qur'an and by His Messenger (saws). Paradise as wide as heaven and earth has been prepared for them. One of their characteristics is that they (interpretation of the meaning) “spend (in Allah's Cause) in prosperity and in adversity, [they] repress anger, and [they] pardon men; verily, Allah loves al-muhsinoon (the good-doers).” [Aal ‘Imraan 3:134]
These are the ones whose good character and beautiful attributes and deeds Allaah has mentioned, and whom people admire and want to emulate. One of their characteristics is that (interpretation of the meaning) “. . . when they are angry, they forgive.” [al-Shooraa 42:47]
