Amr bin Murrah (may Allah have mercy on him) relates: I entered the mosque of Hadramawt, and there was Alqamah bin Wa'il narrating from his father: "The Messenger of Allah (peace and blessings be upon him) used to raise his hands before the bowing (ruku') and after it." I mentioned this to Ibrahim, and he became angry and said: He saw it, and Ibn Mas'ud and his companions did not see it?!
