[Machine] The Messenger of Allah ﷺ did not used to pray the night prayer sitting until he became old. He used to recite while sitting, and when he wanted to bow, he stood up and recited about thirty or forty verses, then he bowed.
لَمْ تَرَ رَسُولَ اللهِ ﷺ يُصَلِّي صَلَاةَ اللَّيْلِ قَاعِدًا قَطُّ حَتَّى أَسَنَّ فَكَانَ يَقْرَأُ قَاعِدًا حَتَّى إِذَا أَرَادَ أَنْ يَرْكَعَ قَامَ فَقَرَأَ نَحْوًا مِنْ ثَلَاثِينَ أَوْ أَرْبَعِينَ آيَةً ثُمَّ رَكَعَ
