وَعَنْ أَبِي هُرَيْرَةَ رضى الله عنه
قَالَ: قَالَ رَسُولُ اَللَّهِ: «اَلْمُسْتَبَّانِ مَا قَالَا، فَعَلَى اَلْبَادِئِ، مَا لَمْ يَعْتَدِ اَلْمَظْلُومُ»
“When two men insult one another, what they say is mainly the fault of the one who began it, so long as the one who is oppressed does not transgress.” Related by Muslim.
