Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي هَاشِمٍ، عَنْ أَبِي مِجْلَزٍ، عَنْ قَيْسِ بْنِ عُبَادٍ، عَنْ أَبِي ذَرٍّ ـ رضى الله عنه ـ قَالَ نَزَلَتْ {هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ} فِي سِتَّةٍ مِنْ قُرَيْشٍ عَلِيٍّ وَحَمْزَةَ وَعُبَيْدَةَ بْنِ الْحَارِثِ وَشَيْبَةَ بْنِ رَبِيعَةَ وَعُتْبَةَ بْنِ رَبِيعَةَ وَالْوَلِيدِ بْنِ عُتْبَةَ.
