Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever has entered into the state of Ihram for both Hajj and Umrah, then one Tawaf will suffice for both of them. Then he should not exit the state of Ihram until he completes his Hajj. Then (on the 10th of Dhul-Hijjah) he should exit the Ihram for both together."
