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. (Using translation from Abū Dāʾūd 953)
مَا رَأَيْتُ رَسُولَ اللهِ ﷺ يَقْرَأُ فِي شَيْءٍ مِنْ صَلَاةِ اللَّيْلِ جَالِسًا حَتَّى دَخَلَ فِي السِّنِّ فَكَانَ يَجْلِسُ فَيَقْرَأُ حَتَّى إِذَا غَبَرَ مِنَ السُّورَةِ ثَلَاثُونَ أَوْ أَرْبَعُونَ آيَةً قَامَ فَقَرَأَ بِهَا ثُمَّ رَكَعَ
