The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 2697
'A'isha (Allah be pleased with her) reported: I used to perfume the Apostle of Allah (may peace be upon him) with a perfume containing musk before entering upon the state of Ihram and on the day of sacrifice (10th of Dhu'l-Hijja) and (at the conclusion of Ihram) before circumambulating the House (for Tawaf-i-Ifada).
