Musnad Ahmad 291:2

Abu Nu'aym narrated to us, he said: Zakariya narrated to us, from al-Sha'bi, he said: Urwah ibn Mudarris ibn Aws ibn Harithah ibn Lam narrated to me, that he performed Hajj during the time of the Messenger of Allah, peace and blessings of Allah be upon him. He did not catch up with the people until nightfall while he was at Jam' (Muzdalifah). So he went to Arafat and departed from it, then he returned and came to Jam'. He said: "O Messenger of Allah, I have exhausted myself and worn out my riding beast, so is there any Hajj for me?" He said: "Whoever prays the morning prayer with us at Jam', and stands with us until we depart, and has already departed from Arafat before that, by night or by day, then his Hajj is complete and he has fulfilled his rites."
