‘A’ishah said:
I used to sleep with my legs in front of the Messenger of Allah ﷺ 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 ﷺ يُصَلِّي وَأَنَا مُعْتَرِضَةٌ بَيْنَ يَدَيْهِ فَإِذَا أَرَادَ أَنْ يَسْجُدَ غَمَزَ رِجْلِي فَضَمَمْتُهَا إِلَىَّ ثُمَّ يَسْجُدُ .
