Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates this statement of the Noble Prophet (peace and blessings be upon him): "Whoever combines Hajj and Umrah, then one Tawaf will suffice for both of them, and such a person will not exit the state of Ihram until the day of sacrifice arrives; then he will exit the Ihram for both at the same time."
