Ibn 'Abbas said, "Two men defamed one another in the time of the Messenger of Allah, (ﷺ). One of them reviled the other who remained silent. The Prophet, (ﷺ), remained seated. Then the other man answered him back and the Prophet, (ﷺ), got up. He was asked, "You got up?" He said, "The angels left, so I left with them. While this man was silent, the angels were answering the one who cursed him. When he answered, the angels left."

حَدَّثَنَا مُحَمَّدُ بْنُ أُمَيَّةَ، قَالَ‏:‏ حَدَّثَنَا عِيسَى بْنُ مُوسَى، عَنْ عَبْدِ اللهِ بْنِ كَيْسَانَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ قَالَ‏:‏ اسْتَبَّ رَجُلاَنِ عَلَى عَهْدِ رَسُولِ اللهِ صلى الله عليه وسلم، فَسَبَّ أَحَدُهُمَا وَالْآخَرُ سَاكِتٌ، وَالنَّبِيُّ صلى الله عليه وسلم جَالِسٌ، ثُمَّ رَدَّ الْآخَرُ‏.‏ فَنَهَضَ النَّبِيُّ صلى الله عليه وسلم، فَقِيلَ‏:‏ نَهَضْتَ‏؟‏ قَالَ‏:‏ نَهَضَتِ الْمَلاَئِكَةُ فَنَهَضْتُ مَعَهُمْ، إِنَّ هَذَا مَا كَانَ سَاكِتًا رَدَّتِ الْمَلاَئِكَةُ عَلَى الَّذِي سَبَّهُ، فَلَمَّا رَدَّ نَهَضَتِ الْمَلاَئِكَةُ‏.‏
