It was narrated from Qabisah bin Hulb that his father said: “The Prophet used to lead us in prayer, and he would take hold of his left hand with his right.”
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ قَبِيصَةَ بْنِ هُلْبٍ، عَنْ أَبِيهِ، قَالَ كَانَ النَّبِيُّ ـ صلى الله عليه وسلم ـ يَؤُمُّنَا فَيَأْخُذُ شِمَالَهُ بِيَمِينِهِ .
