Sahih Muslim Book - 32, Hadith - 4661

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى الْقَيْسِىُّ حَدَّثَنَا الْمُعْتَمِرُ عَنْ أَبِيهِ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ قِيلَ لِلنَّبِىِّ -صلى الله عليه وسلم- لَوْ أَتَيْتَ عَبْدَ اللَّهِ بْنَ أُبَىٍّ قَالَ فَانْطَلَقَ إِلَيْهِ وَرَكِبَ حِمَارًا وَانْطَلَقَ الْمُسْلِمُونَ وَهِىَ أَرْضٌ سَبِخَةٌ فَلَمَّا أَتَاهُ النَّبِىُّ -صلى الله عليه وسلم- قَالَ إِلَيْكَ عَنِّى فَوَاللَّهِ لَقَدْ آذَانِى نَتْنُ حِمَارِكَ. قَالَ فَقَالَ رَجُلٌ مِنَ الأَنْصَارِ وَاللَّهِ لَحِمَارُ رَسُولِ اللَّهِ -صلى الله عليه وسلم- أَطْيَبُ رِيحًا مِنْكَ - قَالَ - فَغَضِبَ لِعَبْدِ اللَّهِ رَجُلٌ مِنْ قَوْمِهِ - قَالَ - فَغَضِبَ لِكُلِّ وَاحِدٍ مِنْهُمَا أَصْحَابُهُ - قَالَ - فَكَانَ بَيْنَهُمْ ضَرْبٌ بِالْجَرِيدِ وَبِالأَيْدِى وَبِالنِّعَالِ - قَالَ - فَبَلَغَنَا أَنَّهَا نَزَلَتْ فِيهِمْ (وَإِنْ طَائِفَتَانِ مِنَ الْمُؤْمِنِينَ اقْتَتَلُوا فَأَصْلِحُوا بَيْنَهُمَا ).

It was narrated that Anas bin Malik said: "It was said to the Prophet (s.a.w): 'Why don't you go to 'Abdullah bin Ubayy?' So he went to him, riding a donkey, and the Muslims set out too, and (they passed over) saline ground. When the Prophet (s.a.w) came to him, he said: 'Do not come near me, for by Allah the stench of your donkey offends me.' One of the Ansar said: 'By Allah, the donkey of the Messenger of Allah (s.a.w) smells better than you do.' One of 'Abdullah's people got angry on his behalf, and the two groups got angry with one another and struck one another with palm branches, hands and shoes. And we . heard that the following words were revealed concerning them: 'And if two parties (or groups) among the believers fall to fighting, then make peace between them both."'
