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

أَنَّ رَجُلًا مِنَ الْأَنْصَارِ وَقَعَ فِي أَبِي الْعَبَّاسِ كَانَ فِي الْجَاهِلِيَّةِ فَلَطَمَهُ الْعَبَّاسُ فَجَاءَ قَوْمَهُ فَقَالُوا وَاللهِ لَنَلْطِمَنَّهُ كَمَا لَطَمَهُ فَلَبِسُوا السِّلاحَ فَبَلَغَ ذَلِكَ رَسُولَ اللهِ ﷺ فَصَعِدَ الْمِنْبَرَ فَقَالَ أَيُّهَا النَّاسُ أَيُّ أَهْلِ الْأَرْضِ أَكْرَمُ عَلَى اللهِ؟ قَالُوا أَنْتَ قَالَ فَإِنَّ الْعَبَّاسَ مِنِّي وَأَنَا مِنْهُ فَلا تَسُبُّوا أَمْوَاتَنَا فَتُؤْذُوا أَحْيَاءَنَا فَجَاءَ الْقَوْمُ فَقَالُوا يَا رَسُولَ اللهِ نَعُوذُ بِاللهِ مِنْ غَضَبِكَ  

[Machine] A man fell into a well that belonged to Al-Abbas during the pre-Islamic era. Al-Abbas slapped him, so the man went to his people and they said, "By Allah, we will slap him back!" They took up their weapons, and this news reached the Prophet Muhammad ﷺ. He ascended the pulpit and said, "O people, O people of the earth, do you know who is the most noble in the sight of Allah?" They replied, "You are, O Messenger of Allah." He said, "Indeed, Al-Abbas is from me and I am from him. Do not insult our deceased, for it hurts our living." The people then came and said, "O Messenger of Allah, we seek refuge in Allah from your anger. Please seek forgiveness for us."

"عَنِ ابْنِ عَبَّاسٍ: أَنَّ رَجُلا مِنَ الأنصارِ وَقَعَ فِى أَبٍ لِلْعَبَّاسِ كَانَ فِى الْجَاهِلِيَّةِ فَلَطَمَهُ الْعَبَّاسُ، فَجَاءَ قَوْمُهُ فَقَالُوا: وَاللهِ لَنَلْطمَنَّهُ كَاللَّطمَةِ حَتَّى لَبِسُوا السَلاحَ، فَبَلَغَ ذَلِكَ رَسُولَ اللهِ ﷺ فَغَضِب، فَجَاءَ فَصَعِدَ المِنْبَرَ فَقَالَ: مَنْ أَنَا؟ فَقَالُوا: أَنْتَ رَسُولُ اللهِ، قَالَ: فَإِنَّ عَمَّ الرَّجُلِ صِنْوُ أَبِيهِ لا تَسُبُّوا أَموَاتَنَا فَتُؤْذُوا أَحْيَاءَنَا، فَقَالُوا: يَا رَسُولَ اللهِ! نَعُوذُ بِاللهِ مِنْ غَضَبِكَ، فَاسْتَغْفِر لَنَا، فَاسْتَغْفرَ لَهُم".
