In-book no 168أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ سَمِعْتُ الْقَاسِمَ بْنَ مُحَمَّدٍ، يُحَدِّثُ عَنْ عَائِشَةَ، قَالَتْ لَقَدْ رَأَيْتُمُونِي مُعْتَرِضَةً بَيْنَ يَدَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَرَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي فَإِذَا أَرَادَ أَنْ يَسْجُدَ غَمَزَ رِجْلِي فَضَمَمْتُهَا إِلَىَّ ثُمَّ يَسْجُدُ .
It was narrated that 'Aishah said: "I remember lying in front of the Messenger of Allah (ﷺ), and the Messenger of Allah (ﷺ) was praying. When he wanted to prostrate he would nudge my foot and I would draw it up (out of the way) until he had finished prostrating."
