What effect did A'isha (Allah be pleased with her) observe when perfuming the Prophet Muhammad (saw) before entering the state of Ihram and on the day of sacrifice (10th of Dhu'l-Hijja)?
 '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).
