حَدَّثَنَا عَاصِمُ بْنُ النَّضْرِ، حَدَّثَنَا الْمُعْتَمِرُ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ أَبِي النَّضْرِ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ كُنْتُأَكُونُ نَائِمَةً وَرِجْلاَىَ بَيْنَ يَدَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ يُصَلِّي مِنَ اللَّيْلِ فَإِذَا أَرَادَ أَنْ يَسْجُدَ ضَرَبَ رِجْلَىَّ فَقَبَضْتُهُمَا فَسَجَدَ ‏.‏

It was reported from Abu An-Nadr, from Abu Salama bin 'Abdur Rahman, from 'Aishah, that she said

I used to sleep with my legs stretched out in front of the Messenger of Allah (ﷺ) while he was praying at night. When he wanted to prostrate, he would pinch my legs, so I would draw them in, and then he would prostrate.
