Nafi' narrates from Ibn Umar (may Allah be pleased with him) that when he perfumed himself with incense, he would burn aloeswood (aluwwah) without mixing other scents with it, and he would also burn camphor together with the aloeswood. Then he would say: "This is how the Messenger of Allah (peace and blessings be upon him) used to perfume himself with incense."
