The good deed and the evil deed cannot be equal. Repel (the evil) with one which is better (i.e. Allâh ordered the faithful believers to be patient at the time of anger, and to excuse those who treat them badly), then verily! he, between whom and you there was enmity, (will become) as though he was a close friend.

But none is granted it (the above quality) except those who are patient, and none is granted it except the owner of the great portion (of the happiness in the Hereafter i.e. Paradise and in this world of a high moral character).

(Fussilat 41:34-35)
