حَدَّثَنَا ابْنُ أَبِي عُمَرَ ، حَدَّثَنَا بِشْرُ بْنُ السَّرِيِّ ، ح قَالَ وَحَدَّثَنَا ابْنُ خِرَاشٍ ، حَدَّثَنَا عَمْرُو بْنُ عَاصِمٍ ، قَالاَ جَمِيعًا حَدَّثَنَا هَمَّامٌ ، بِهَذَا الإِسْنَادِ وَنَسَبَا أَبَا بَكْرٍ فَقَالاَ ابْنُ أَبِي مُوسَى .
This hadith has been narrated by the same chain of transmitters by Hammam, and said about Abu Bakr that he was Ibn Abu Musa.
