Sahih Muslim , Book 19, Hadith 9 (In-Book) ⓘ
Sa'id b. Jubair reported that Mus'ab b. Zubair did not effect separation between the Mutala'inain (invokers of curses). Sa'id said: It was mentioned to 'Abdullah b. Umar (Allah be pleased with them) and he said: Allah's Apostle effected separation between the two members of Banu al-'Ajlan.
وَحَدَّثَنَا أَبُو غَسَّانَ الْمِسْمَعِيُّ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ - وَاللَّفْظُ لِلْمِسْمَعِيِّ وَابْنِ الْمُثَنَّى - قَالُوا حَدَّثَنَا مُعَاذٌ، - وَهُوَ ابْنُ هِشَامٍ - قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ عَزْرَةَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ لَمْ يُفَرِّقِ الْمُصْعَبُ بَيْنَ الْمُتَلاَعِنَيْنِ . قَالَ سَعِيدٌ فَذُكِرَ ذَلِكَ لِعَبْدِ اللَّهِ بْنِ عُمَرَ . فَقَالَ فَرَّقَ نَبِيُّ اللَّهِ صلى الله عليه وسلم بَيْنَ أَخَوَىْ بَنِي الْعَجْلاَنِ .
