Abdullah bin Shaqiq said: I asked Aishah whether the Messenger of Allah ﷺ recited a whole Surah (of the Quran) in one Rak’ah of the prayer. She replied: (He recited from among) the Mufassal surahs. I asked: Did he pray (at night) sitting? She replied: (he prayed sitting) when the people made him old.

956. Commentary:
➊ That is, it is not appropriate to perform the prayer sitting without a valid excuse.
➋ The continuous engagement in da'wah (invitation to Islam), tazkiyah (spiritual purification), jihad (struggle in the path of Allah), and the most strenuous acts of worship had indeed exhausted the Prophet sallallahu alayhi wa sallam.
➌ It is also permissible to recite more than one surah in a single rak'ah.
