(Ashoora) 42 : 37
وَالَّذِينَ يَجْتَنِبُونَ كَبَائِرَ الْإِثْمِ وَالْفَوَاحِشَ وَإِذَا مَا غَضِبُوا هُمْ يَغْفِرُونَ
And those who are abstaining from the heinous sins and the shameful deeds; and when they become angry, they will forgive.
From the heedful who keeps Allah in the heart with Adhikr (the Truth), no heinous or shameful deed happens. Such a believer who is the vicegerent of Believer Allah, if he happens to face any deed or word from the ignorant people angering him, he, without becoming angry, will behave in a forgiving manner. See explanation 4: 31; 9: 80 and 29: 45.
