The hadith has been narrated on the authority ot al-A'mash with the same chain of transmitters but no mention is made of:" They are my companions; they are my companions."
وَحَدَّثَنَاهُ عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، عَنْ جَرِيرٍ، عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ . وَلَمْ يَذْكُرْ " أَصْحَابِي أَصْحَابِي " .
