The Qur'an 42:47 speaks of forgiveness, "And those who avoid major sins and immoralities and when angry they forgive" The glorious Qur'an (15:58) speaks also of kindness and wing lowering, "and lower your wing (show kindness) to the believers." In addition to these two virtues, the Qur'an 5:54 talks about humility, "they are humble toward the believers." Getting angry is nothing to be proud of; it is not even a sign of strength. The Prophet (peace and blessings be unto him) said," Strong is not the one who wrestles others to the ground, but strong is the one who controls himself when angry." The Prophet (peace and blessings be unto him) said, "I am warning you of zun which is thinking badly of others; zun is the most unreliable form of interaction; don't follow each other's shortcomings; don't spy on each other; don't envy each other; don't hate one another; don't plan evil to each other; be true servants of Allah-brothers in faith." The last four virtues of forgiveness, kindness, humility and zun-avoidance bundle together to develop a shield against anger.
