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 ‏.‏

It was narrated from Maimunah that: When the Prophet (ﷺ) prostrated he would hold his arms out from his sides so that if a lamb wanted to pass beneath his arms it would be able to do so.
