Abdullah (b. 'Umar) reported that whenever Allah's Messenger ( صلی اللہ علیہ وسلم ) entered Mecca, he got down at Dhi Tuwa and spend the night there until he observed the dawn prayer. And Allah's Messenger ( صلی اللہ علیہ وسلم ) 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.
