Abdullah bin Amr said: It has been narrated to me that the Messenger of Allah ﷺ said: The Prayer of a man in sitting condition is half the prayer (wins him half the reward of prayer). I came to him and found him prayer in sitting condition. I placed my hand on my head (in surprise). He said: what is the matter, Abdullah bin Amr? I said; Messenger of Allah ﷺ you have been reported to me as saying: the prayer of a man in sitting condition is half the prayer, but you are praying in sitting condition. He said: yes, but I am not like one of you.

Abdullah bin Buraidah said: Imran bin Hussain asked the prophet ﷺ about the prayer a man offers in sitting condition. He replied: his prayer in standing condition is better than his prayer in sitting condition, and his prayer in sitting condition is half the prayer he offers in standing condition, and his prayer in lying condition is half the prayer he offers in sitting condition.

Imran bin Husain said: I had a fistula; so I asked the prophet ﷺ. He said: offer prayer in standing condition; if you are unable to do so, then in sitting condition: if you are then at your side (i. e, in lying condition).

Aishah said: 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.

Aishah, wife of the prophet ﷺ, said: when the prophet ﷺ prayed sitting, he recited the Quran in sitting condition. When the amount of his recitation remained about thirty or forty verses he stood up and recited them standing. He then bowed and prostrated and then did so in the second Rak’ah of the prayer. Abu Dawud said: Alqamah bin Waqqas narrated this tradition on the authority of Aishah from the Prophet ﷺ to the same effect.

Aishah said: The Messenger of Allah ﷺ used to pray standing at night for a long time, and used to pray sitting at night for a long time. When he prayed standing, he bowed standing, and when he prayed sitting, he bowed sitting.

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.
