Chapter 16: The Book of Pilgrimage
Abdullah (b. 'Umar) reported that whenever Allah' s Messenger (ﷺ) entered Mecca, he got down at Dhi Tuwa and spend the night there until he observed the dawn prayer. And Allah' s Messenger (ﷺ) observed this prayer on a rough hillock, and not in the mosque which had been then built there, but to the lower side of it (the mosque) on a hillock.
