Urwah narrates that I heard Aisha (may Allah be pleased with her) say: I applied perfume to the Messenger of Allah (peace and blessings be upon him) for entering into Ihram and for coming out of Ihram. Urwah says: I asked Aisha (may Allah be pleased with her), "Which perfume?" She replied: "The best perfume." Uthman says: Hisham did not narrate this hadith from anyone except me.
