Abu Wa'il (may Allah have mercy on him) said: Sayyiduna Ali (may Allah be pleased with him) had some musk, and he instructed that he be perfumed with it (after death), and Sayyiduna Ali (may Allah be pleased with him) said: It is what remained of the perfume used for the Messenger of Allah (peace and blessings be upon him) (at his death).
