Zuhayr ibn Harb narrated to me, saying: Yahya—namely al-Qattan—narrated to us. (Another chain:) Abu Bakr ibn Abi Shaybah narrated to us, saying: Abu Usamah narrated to us. (Another chain:) Ibn Numayr narrated to us—and the wording is his—saying: Abdah narrated to us, from Ubaydullah, from Nafi', from Ibn Umar, who said: The Messenger of Allah (peace and blessings be upon him) entered the House (the Ka'bah) with Usamah, Bilal, and Uthman ibn Talhah. They closed the door upon themselves for a long time, then it was opened. I was the first to enter, and I met Bilal and asked him: "Where did the Messenger of Allah (peace and blessings be upon him) pray?" He said: "Between the two front pillars." But I forgot to ask him how many units (rak'ahs) the Messenger of Allah (peace and blessings be upon him) prayed.
