a man slandered one of his forefathers from the time of the Jahiliyyah, and Al-'Abbas slapped him. His people came and said: "Let him slap him as he slapped him," and they prepared for quarrel. News of that reached the Prophet, and he ascended the Minbar and said: "O People, which of the people of the Earth do you know to be the most noble before Allah?" They said: "You." He said: "Al-Abbas belongs to me and I to him. Do not defame our dead or offend our living." Those people came and said: "O Messenger of Allah, we seek refuge with Allah from your anger; pray to give us."  

أَنَّ رَجُلاً وَقَعَ فِي أَبٍ كَانَ لَهُ فِي الْجَاهِلِيَّةِ فَلَطَمَهُ الْعَبَّاسُ فَجَاءَ قَوْمُهُ فَقَالُوا لَيَلْطِمَنَّهُ كَمَا لَطَمَهُ فَلَبِسُوا السِّلاَحَ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَصَعِدَ الْمِنْبَرَ فَقَالَ أَيُّهَا النَّاسُ أَىُّ أَهْلِ الأَرْضِ تَعْلَمُونَ أَكْرَمُ عَلَى اللَّهِ ﷻ فَقَالُوا أَنْتَ فَقَالَ إِنَّ الْعَبَّاسَ مِنِّي وَأَنَا مِنْهُ لاَ تَسُبُّوا مَوْتَانَا فَتُؤْذُوا أَحْيَاءَنَا فَجَاءَ الْقَوْمُ فَقَالُوا يَا رَسُولَ اللَّهِ نَعُوذُ بِاللَّهِ مِنْ غَضَبِكَ اسْتَغْفِرْ لَنَا
