Nafi' narrates from Ibn Umar (may Allah be pleased with him) that when he perfumed himself on Friday, he would burn incense of aloeswood ('ud) without mixing any other scent with it, but he would add camphor to it, and he would say: This is the perfume of the Messenger of Allah (peace and blessings be upon him).
