Disparaging
Reviling a Muslim is deviant behaviour
حَدَّثَنَا عُمَرُ، قَالَ: حَدَّثَنَا أَبِي، قَالَ: حَدَّثَنَا الأَعْمَشُ، قَالَ: حَدَّثَنَا عَدِيُّ بْنُ ثَابِتٍ قَالَ: سَمِعْتُ سُلَيْمَانَ بْنَ صُرَدٍ، رَجُلاً مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم، قَالَ: اسْتَبَّ رَجُلاَنِ عِنْدَ النَّبِيِّ صلى الله عليه وسلم فَغَضِبَ أَحَدُهُمَا، فَاشْتَدَّ غَضَبُهُ حَتَّى انْتَفَخَ وَجْهُهُ وَتَغَيَّرَ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم: إِنِّي لَأَعْلَمُ كَلِمَةً لَوْ قَالَهَا لَذَهَبَ عَنْهُ الَّذِي يَجِدُ، فَانْطَلَقَ إِلَيْهِ الرَّجُلُ، فَأَخْبَرَهُ بِقَوْلِ النَّبِيِّ صلى الله عليه وسلم وَقَالَ: تَعَوَّذْ بِاللَّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ، وَقَالَ: أَتَرَى بِي بَأْسًا، أَمَجْنُونٌ أَنَا؟ اذْهَبْ.
Sulayman ibn Surad, one of the Companions of the Prophet, said, "Two men reviled one another in the presence of the Prophet, (ﷺ), and one of them became angry. He became so angry that his face puffed out and changed colour. The Prophet, (ﷺ), 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, (ﷺ), 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!'"
