Abu Dawud
The Rites of Hajj
Book Number: 004 / Hadith Number: 1945
Narated By Urwah ibn Mudarris at-Ta'i : I came to the Apostle of Allah (pbuh) at the place of halting, that is, al-Muzdalifah. I said: I have come from the mountains of Tayy. I fatigued my mount and fatigued myself. By Allah, I found no hill (on my way) but I halted there. Have I completed my hajj? The Apostle of Allah (pbuh) said: Anyone who offers this prayer along with us and comes over to Arafat before it by night or day will complete his hajj and he may wash away the dirt (of his body).
