Two men abused each other in front of the Prophet ﷺ while we were sitting with him. One of the two abused his companion furiously and his face became red. The Prophet ﷺ said, "I know a word (sentence) the saying of which will cause him to relax if this man says it. Only if he said, "I seek refuge with Allah from Satan, the outcast.' " So they said to that (furious) man, 'Don't you hear what the Prophet ﷺ is saying?" He said, "I am not mad."

اسْتَبَّ رَجُلاَنِ عِنْدَ النَّبِيِّ ﷺ وَنَحْنُ عِنْدَهُ جُلُوسٌ وَأَحَدُهُمَا يَسُبُّ صَاحِبَهُ مُغْضَبًا قَدِ احْمَرَّ وَجْهُهُ فَقَالَ النَّبِيُّ ﷺ إِنِّي لأَعْلَمُ كَلِمَةً لَوْ قَالَهَا لَذَهَبَ عَنْهُ مَا يَجِدُ لَوْ قَالَ أَعُوذُ بِاللَّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ فَقَالُوا لِلرَّجُلِ أَلاَ تَسْمَعُ مَا يَقُولُ النَّبِيُّ ﷺ قَالَ إِنِّي لَسْتُ بِمَجْنُونٍ

A man from the companions of the Prophet ﷺ said, "Two men abused each other in front of the Prophet ﷺ and one of them became angry and his anger became so intense that his face became swollen and changed. The Prophet ﷺ said, "I know a word the saying of which will cause him to relax if he does say it." Then a man went to him and informed him of the statement of the Prophet ﷺ and said, "Seek refuge with Allah from Satan." On that, angry man said, 'Do you find anything wrong with me? Am I insane? Go away!"

اسْتَبَّ رَجُلاَنِ عِنْدَ النَّبِيِّ ﷺ فَغَضِبَ أَحَدُهُمَا فَاشْتَدَّ غَضَبُهُ حَتَّى انْتَفَخَ وَجْهُهُ وَتَغَيَّرَ فَقَالَ النَّبِيُّ ﷺ إِنِّي لأَعْلَمُ كَلِمَةً لَوْ قَالَهَا لَذَهَبَ عَنْهُ الَّذِي يَجِدُ فَانْطَلَقَ إِلَيْهِ الرَّجُلُ فَأَخْبَرَهُ بِقَوْلِ النَّبِيِّ ﷺ وَقَالَ تَعَوَّذْ بِاللَّهِ مِنَ الشَّيْطَانِ فَقَالَ أَتُرَى بِي بَأْسٌ أَمَجْنُونٌ أَنَا اذْهَبْ
