Arabic (Original)
حَدَّثَنَا عَبْد اللَّهِ حَدَّثَنِي أَبِي حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ سُفْيَانَ عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى عَنْ مُعَاذٍ قَالَ اسْتَبَّ رَجُلَانِ عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَغَضِبَ أَحَدُهُمَا فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنِّي لَأَعْلَمُ كَلِمَةً لَوْ قَالَهَا ذَهَبَ غَضَبُهُ أَعُوذُ بِاللَّهِ مِنْ الشَّيْطَانِ الرَّجِيمِ.
English Translation
Abdullah told us, my father told me, Abd al-Rahman ibn Mahdi told us, from Sufyan, from Abd al-Malik ibn 'Umayr, from Abd al-Rahman ibn Abi Layla, from Mu'adh, who said: Two men reviled one another in the presence of the Prophet, peace and blessings be upon him, and one of them grew angry, so the Prophet, peace and blessings be upon him, said: "Indeed I know a word which, if he said it, his anger would leave him: 'I seek refuge in Allah from Satan, the accursed.'"
