It is narrated from Aisha (may Allah be pleased with her) that she said: I applied perfume with my own hands to the Messenger of Allah (peace and blessings be upon him) for Ihram when he entered into Ihram, and likewise for becoming lawful (halal) after the circumambulation (Tawaf) of the House of Allah, before he became lawful.
