It is narrated from Sayyiduna Umar Farooq (may Allah be pleased with him) that I heard the Prophet (peace and blessings be upon him) saying in the valley of Aqiq: "Tonight a messenger came to me from my Lord and said, 'Pray in this blessed valley and enter into the state of Ihram with the intention of both Hajj and Umrah.'" The place referred to is Dhu'l-Hulayfah.
