1174 – Ibn Masʿūd (may Allah be pleased with him) said: “I prayed with the Prophet (peace and blessings be upon him) one night, and he remained standing so long that I was on the verge of doing something improper.” It was asked, “What were you about to do?” He replied, “I thought of sitting down and leaving him.” Agreed upon.

1175 – Hudhayfah (may Allah be pleased with him) said: “I prayed with the Prophet (peace and blessings be upon him) one night. He began reciting Sūrah al-Baqarah, and I thought, ‘He will bow at the hundredth verse.’ But he continued. I then thought, ‘He will finish the sūrah in one rakʿah,’ yet he went on. I next thought, ‘He will bow after it,’ but he opened Sūrah al-Nisā’ and recited it, then opened Sūrah Āl ʿImrān and recited it. He recited slowly and deliberately; whenever he passed a verse that contained glorification he glorified, whenever he came to a verse of petition he asked, and whenever he reached a verse of seeking refuge he sought refuge. Then he bowed, repeatedly saying, ‘Subḥāna rabbiyal-ʿaẓīm (Glory be to my Lord, the Majestic),’ and his bowing lasted about as long as his standing. After rising he said, ‘Samiʿa-Allāhu liman ḥamidah, rabbanā wa laka al-ḥamd (Allah hears those who praise Him; our Lord, to You belongs all praise),’ and he stood nearly as long as he had bowed. He then prostrated, saying, ‘Subḥāna rabbiyal-aʿlā (Glory be to my Lord, the Most High),’ and his prostration was approximately as long as his standing.” Reported by Muslim.

[Explanation]
These hadiths describe the Prophet’s night prayer. Among them is the first narration of ʿĀʾishah, which states that the Prophet (peace and blessings be upon him) used to perform eleven rakʿahs at night, and other reports clarify that he would end with the taslīm after every two rakʿahs, then
