Musnad Ahmad 1153:1988

Yazid narrated to us, he said: Muhammad ibn ‘Amr informed us, from his father, from his grandfather ‘Alqamah ibn Waqqas, from ‘Aishah, that she said: I used to apply perfume to the Messenger of Allah, peace and blessings of Allah be upon him, when he entered into the state of Ihram, and when he exited it.
