Narrated `Abdullah bin Buraida: `Imran bin Husain had piles. Once Abu Ma mar narrated from `Imran bin Husain had said, "I asked the Prophet (p.b.u.h) about the prayer of a person while sitting. He said, 'It is better for one to pray standing; and whoever prays sitting gets half the reward of that who prays while standing; and whoever prays while Lying gets half the reward of that who prays while sitting.' "

Narrated `Imran bin Husain: had piles, so I asked the Prophet about the prayer. He said, "Pray while standing and if you can't, pray while sitting and if you cannot do even that, then pray Lying on your side."

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.
