Mukhtasar Bukhari

Narrated Abdullah bin Umar (may Allah be pleased with them) that the Prophet (peace and blessings of Allah be upon him) used to stay at (the place of) Dhi Tuwa and would spend the night there until morning came, and he would offer the morning prayer there (this was) when he came to Makkah. And the place where the Messenger of Allah (peace and blessings of Allah be upon him) used to pray is on a hard hill, not in the mosque that has been built there, but rather below it, on that same hard hill.
