Narrated Abu Salma bin `Abdur Rahman
I asked `Aisha, "How is the prayer of Allah's Messenger (ﷺ) during the month of Ramadan." She said, "Allah's Messenger (ﷺ) never exceeded eleven rak`at in Ramadan or in other months; he used to offer four rak`at-- do not ask me about their beauty and length, then four rak`at, do not ask me about their beauty and length, and then three rak`at." Aisha further said, "I said, 'O Allah's Messenger (ﷺ)! Do you sleep before offering the witr prayer?' He replied, 'O `Aisha! My eyes sleep but my heart remains awake'!"
Narrated `Aisha
I did not see the Prophet (ﷺ) 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.
