‘Abd ibn Humayd narrated to us, ‘Abd al-Razzaq informed us, Ma‘mar informed us, from al-Zuhri, from ‘Ata’, the freed slave of Siba‘, from Usamah ibn Zayd, that he was riding behind the Messenger of Allah (peace and blessings be upon him) when he departed from ‘Arafat. When he reached the mountain pass, he made his camel kneel, then went to relieve himself. When he returned, I poured water for him from the water vessel, and he performed ablution. Then he mounted, then came to Muzdalifah, where he combined the Maghrib and ‘Isha’ prayers.
