Yahya ibn Yahya narrated to us: Sufyan ibn 'Uyaynah informed us, from Abu Ya'fur—whose name is Waqid and whose nickname is Waqdan—(H). And Abu Bakr ibn Abi Shaybah and Abu Kurayb narrated to us, both saying: Abu Mu'awiyah narrated to us, from al-A'mash, both of them from Muslim, from Masruq, from 'A'ishah, who said: "The Messenger of Allah (peace be upon him) performed the Witr prayer at every part of the night, and his Witr ultimately came to be at the time of sahur (the last part of the night before dawn)."
