Narrated Aisha: (the mother of the faithful believers) I never saw Allah's Apostle offering the night prayer while sitting except in his old age and then he used to recite while sitting and whenever he wanted to bow he would get up and recite thirty or forty verses (while standing) and then bow.

Narrated `Aisha: (the mother of the faithful believers) Allah's Apostle (in his last days) used to pray sitting. He would recite while sitting, and when thirty or forty verses remained from the recitation he would get up and recite them while standing and then he would bow and prostrate. He used to do the same in the second rak`a. After finishing the Prayer he used to look at me and if I was awake he would talk to me and if I was asleep, he would lie down.

Narrated `Aisha: I did not see the Prophet reciting (the Qur'an) in the night prayer while sitting except when he became old; when he used to recite while sitting, and when thirty or forty verses remained from the Sura, he would get up and recite them and then bow.

Narrated `Aisha: After offering the Sunna of the Fajr prayer, the Prophet used to talk to me, if I happen to be awake; otherwise he would lie down till the Iqama call was proclaimed (for the Fajr prayer).

Narrated `Aisha: After offering the two rak`at (Sunna) the Prophet (p.b.u.h) used to talk to me, if I happen to be awake; otherwise he would lie down.

Narrated Aisha: The Prophet used to offer prayer at night (for such a long time) that his feet used to crack. I said, "O Allah's Messenger ! Why do you do it since Allah has forgiven you your faults of the past and those to follow?" He said, "Shouldn't I love to be a thankful slave (of Allah)?' When he became old, he prayed while sitting, but if he wanted to perform a bowing, he wound get up, recite (some other verses) and then perform the bowing.
