حَدَّثَنَا حَجَّاجُ بْنُ مِنْهَالٍ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو هَاشِمٍ، عَنْ أَبِي مِجْلَزٍ، عَنْ قَيْسِ بْنِ عُبَادٍ، عَنْ أَبِي ذَرٍّ ـ رضى الله عنه ـ أَنَّهُ كَانَ يُقْسِمُ فِيهَا إِنَّ هَذِهِ الآيَةَ ‏{‏هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ‏}‏ نَزَلَتْ فِي حَمْزَةَ وَصَاحِبَيْهِ، وَعُتْبَةَ وَصَاحِبَيْهِ يَوْمَ بَرَزُوا فِي يَوْمِ بَدْرٍ رَوَاهُ سُفْيَانُ عَنْ أَبِي هَاشِمٍ‏.‏ وَقَالَ عُثْمَانُ عَنْ جَرِيرٍ عَنْ مَنْصُورٍ عَنْ أَبِي هَاشِمٍ عَنْ أَبِي مِجْلَزٍ قَوْلَهُ‏.‏
