Musnad Ahmad 1153:1506

Rawh narrated to us, he said: Shu'bah narrated to us, he said: 'Abd al-Rahman ibn al-Qasim narrated to us, he said: I heard my father narrating from 'Aishah, that she said: "I used to perfume the Messenger of Allah, peace and blessings of Allah be upon him, for his state of ihram when he entered into it, and for his state of hill (non-sacred state) when he exited it, before he performed tawaf around the House."
