حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى قَالَ‏:‏ أَخْبَرَنِي يَحْيَى بْنُ زَكَرِيَّا بْنِ أَبِي زَائِدَةَ، عَنْ زَكَرِيَّا، عَنْ أَبِي إِسْحَاقَ، عَنْ مُحَمَّدِ بْنِ سَعْدِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ‏:‏ سِبَابُ الْمُسْلِمِ فُسُوقٌ‏.‏

Sulayman ibn Surad, one of the Companions of the Prophet, said, "Two men reviled one another in the presence of the Prophet, may Allah bless him and grant him peace, and one of them became angry. He became so angry that his face puffed out and changed colour. The Prophet, may Allah bless him and grant him peace, said, 'I know some words which will make what he feels depart if he says them.' The man came to him and told him what the Prophet, may Allah bless him and grant him peace, had said, He said, 'Seek refuge with Allah from the Accursed Shaytan.' He said, 'Do you think that there is something wrong with me? Am I mad? Leave!'"
