أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللَّهِ، - وَهُوَ ابْنُ عَبْدِ اللَّهِ بْنِ الأَصَمِّ - عَنْ عَمِّهِ، يَزِيدَ - وَهُوَ ابْنُ الأَصَمِّ - عَنْ مَيْمُونَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا سَجَدَ جَافَى يَدَيْهِ حَتَّى لَوْ أَنَّ بَهْمَةً أَرَادَتْ أَنْ تَمُرَّ تَحْتَ يَدَيْهِ مَرَّتْ ‏.‏
