Narrated Hafsa, the wife of the Prophet (Allah bless him and give him peace), said:
“Allah’s Messenger (Allah bless him and give him peace) used to perform voluntary ritual prayer sitting down , and he would recite the Sura and pronounce it slowly, so that it would seem to be longer than one that was actually longer than it.”
“I asked 'A’isha (may Allah be well pleased with her) about the voluntary ritual prayers of Allah’s Messenger (Allah bless him and give him peace), and she said: ‘He used to spend a long night performing the ritual prayer while standing, and a long night while sitting, so if he recited the Qur’an while standing, he would bow and prostrate from a standing position, and if he recited while sitting, he would bow and prostrate from a sitting position.”
Narrated 'A’isha said (may Allah be well pleased with her):
“The Prophet (Allah bless him and give him peace) used to perform the ritual prayer sitting down, so he would also recite the Qur’an while he was seated. If the amount of his recitation remaining was thirty or forty verses, he would rise and recite standing up, and then he would bow and prostrate. Then he would do likewise in the second cycle.”
