What did Prophet Muhammad (peace be upon him) pray when he returned to Medina from Mecca?
 Narrated Ibn `Umar:                     Whenever Allah's Apostle left for Mecca, he used to pray in the mosque of Ash-Shajra, and when he returned (to Medina), he used to pray in the middle of the valley of Dhul-Hulaifa and used to pass the night there till morning.
