I did not see the Messenger of Allah ﷺ reciting (the Qur'an) in the night prayer in a sitting position, till he grew old and then he recited (it) in a sitting position, but when thirty or forty verses were left out of the Surah, he would then stand up, recite them and then bowed.  

مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَقْرَأُ فِي شَىْءٍ مِنْ صَلاَةِ اللَّيْلِ جَالِسًا حَتَّى إِذَا كَبِرَ قَرَأَ جَالِسًا حَتَّى إِذَا بَقِيَ عَلَيْهِ مِنَ السُّورَةِ ثَلاَثُونَ أَوْ أَرْبَعُونَ آيَةً قَامَ فَقَرَأَهُنَّ ثُمَّ رَكَعَ  

"I never saw the Messenger of Allah ﷺ pray sitting down until he grew old. Then he would pray sitting down and when there were thirty or forty verses left, he would stand up and recite them, then bow."  

مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى جَالِسًا حَتَّى دَخَلَ فِي السِّنِّ فَكَانَ يُصَلِّي وَهُوَ جَالِسٌ يَقْرَأُ فَإِذَا غَبَرَ مِنَ السُّورَةِ ثَلاَثُونَ أَوْ أَرْبَعُونَ آيَةً قَامَ فَقَرَأَ بِهَا ثُمَّ رَكَعَ  

I never saw the Messenger of Allah ﷺ reciting the Quraan in his prayer at night in sitting condition until he became old. Then he used to sit in it (the prayer) and recite the Quran until forty or thirty verses remained, then he stood and recited them and prostrated himself.

“I did not see the Messenger of Allah ﷺ offer any of the night prayers in any way other than standing, until he became old. Then he started to pray sitting down until, when there were thirty or forty Verses left of his recitation, he would stand up and recite them, and prostrate.”  

مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُصَلِّي فِي شَىْءٍ مِنْ صَلاَةِ اللَّيْلِ إِلاَّ قَائِمًا حَتَّى دَخَلَ فِي السِّنِّ فَجَعَلَ يُصَلِّي جَالِسًا حَتَّى إِذَا بَقِيَ عَلَيْهِ مِنْ قِرَاءَتِهِ أَرْبَعُونَ آيَةً أَوْ ثَلاَثُونَ آيَةً قَامَ فَقَرَأَهَا وَسَجَدَ
