And Zuhayr ibn Harb and Ubaydullah ibn Sa'id narrated to me, both saying: Yahya—and he is Ibn Sa'id—narrated to us from Ubaydullah, who said: Nafi' informed me, from Ibn 'Umar. (Another chain:) And Abu Bakr ibn Abi Shaybah narrated to us: Abu Usamah narrated to us: Ubaydullah narrated to us, from Nafi', from Ibn 'Umar, who said: I prayed with the Messenger of Allah, peace and blessings be upon him, two prostrations before the noon prayer and two after it, and two after the sunset prayer, and two after the evening prayer, and two after the Friday prayer. As for the sunset, evening, and Friday prayers, I prayed them with the Prophet, peace and blessings be upon him, in his house.
