This tradition has also been transmitted by Muhammad b. Muslim through a different chain of narrators. This version adds; “While he is sitting before he gives the salutation.”
حَدَّثَنَا حَجَّاجُ بْنُ أَبِي يَعْقُوبَ، حَدَّثَنَا يَعْقُوبُ، حَدَّثَنَا ابْنُ أَخِي الزُّهْرِيِّ، عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ، بِهَذَا الْحَدِيثِ بِإِسْنَادِهِ زَادَ " وَهُوَ جَالِسٌ قَبْلَ التَّسْلِيمِ " .
