I prayed with the Messenger of Allah ﷺ at Mina, two rakahs. I also prayed two rakahs with Abu Bakr and Umar, and two rakahs with Uthman during the early part of his rule.
صليت مع رسول الله ﷺ بمنى، ومع أبي بكر وعمر ركعتين، ومع عثمان ركعتين صدرا من إمارته.
Nasai (1447) narrated it from Qutayba, who said, Layth told us, from Bukayr bin Abdullah, from Muhammad bin Abdullah bin Abu Salim, from Anas, and he related it.Its chain of transmission is sahih, on account of Muhammad bin Abdullah bin Abu Salim, who is "truthful" as stated in Taqrib. Nasai deemed him reliable and narrated from him, and Ibn Hibban mentioned him in Thiqat (5/362). So there is no basis for Dhahabi's statement in Mizan that "he is unknown."Imam Ahmad also recorded it (12464) through the hadith of Layth, who is Ibn Saad, with a similar chain.
