It is narrated from Hazrat Anas (may Allah be pleased with him) that I have never smelled ambergris, musk, or any other fragrance more pleasant than the scent of the Prophet (peace and blessings be upon him), and I have never touched silk, brocade, or anything else softer than the Prophet (peace and blessings be upon him).
