This tradition has also been reported by Shu’bah through a different chain of narrators. This version adds:

Bless Muhammad and Muhammad’s family as Thou didst bless Abraham.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا شُعْبَةُ، بِهَذَا الْحَدِيثِ قَالَ
" صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ " .
