'Abdullah b. Shaqiq al-'Uqaili reported: I asked 'A'isha about the prayer of the Messenger of Allah ﷺ during the night (i. e. Tahajjud prayer) She replied: He used to pray for a long time standing and for a long time sitting in the night, and when he recited the Qur'an while standing, he would bow himself from the standing position, and when he recited while sitting, he would bow from the sitting position.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُعَاذُ بْنُ مُعَاذٍ، عَنْ حُمَيْدٍ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ الْعُقَيْلِيِّ، قَالَ سَأَلْتُ عَائِشَةَ عَنْ صَلاَةِ، رَسُولِ اللَّهِ ﷺ بِاللَّيْلِ فَقَالَتْ كَانَ يُصَلِّي لَيْلاً طَوِيلاً قَائِمًا وَلَيْلاً طَوِيلاً قَاعِدًا وَكَانَ إِذَا قَرَأَ قَائِمًا رَكَعَ قَائِمًا وَإِذَا قَرَأَ قَاعِدًا رَكَعَ قَاعِدًا .
