Sulayman ibn Surad reported: Two people insulted each other in the presence of the Messenger of Allah, peace and blessings be upon him, and the eyes of one of them became red like embers and the veins of his neck were bulging. The Prophet said, “Verily, I know a word he could say to calm himself: I seek refuge in Allah from the cursed Satan.”

عَنْ سُلَيْمَانَ بْنِ صُرَدٍ قَالَ اسْتَبَّ رَجُلَانِ عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَجَعَلَ أَحَدُهُمَا تَحْمَرُّ عَيْنَاهُ وَتَنْتَفِخُ أَوْدَاجُهُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنِّي لَأَعْرِفُ كَلِمَةً لَوْ قَالَهَا لَذَهَبَ عَنْهُ الَّذِي يَجِدُ أَعُوذُ بِاللَّهِ مِنْ الشَّيْطَانِ الرَّجِيمِ
