The virtue of the Subh and the `Asr prayers, and of maintaining them
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.
