Sunan Abi Dawud, Hadith 712 ⓘ
‘A’ishah said: I used to sleep with my legs in front of the Messenger of Allah when he would offer his prayer at night (i.e. tahajjud prayer offered towards the end of the night.). When he prostrated himself he struck my legs, and I drew them up and he then prostrated.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ سَمِعْتُ الْقَاسِمَ، يُحَدِّثُ عَنْ عَائِشَةَ، قَالَتْ بِئْسَمَا عَدَلْتُمُونَا بِالْحِمَارِ وَالْكَلْبِ لَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يُصَلِّي وَأَنَا مُعْتَرِضَةٌ بَيْنَ يَدَيْهِ فَإِذَا أَرَادَ أَنْ يَسْجُدَ غَمَزَ رِجْلِي فَضَمَمْتُهَا إِلَىَّ ثُمَّ يَسْجُدُ .
