عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَرَضِيَ اللَّهُ عَنْهَا أَنَّهَا أَخْبَرَتْهُ أَنَّهَا لَمْ تَرَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُصَلِّي فِي سُبْحَتِهِ قَاعِدًا حَتَّى أَسَنَّ، فَكَانَ يَقْرَأُ قَاعِدًا حَتَّى إِذَا أَرَادَ أَنْ يَرْكَعَ قَامَ فَقَرَأَ نَحْوًا مِنْ ثَلَاثِينَ أَوْ أَرْبَعِينَ آيَةً ثُمَّ رَكَعَ
The wife of the Messenger, Sayyida Aisha (may Allah be pleased with her), says: I never saw the Noble Prophet (peace and blessings be upon him) performing prayer at night while sitting, until he became old. Then he (peace and blessings be upon him) would recite while sitting, and when he intended to bow (ruku‘), he would stand up and, after reciting thirty or forty verses, would perform ruku‘.
