Sayyidina Usamah ibn Shank reported that some villagers asked, “O Messenger of Allah! Shall we not take medicine”? He said, “Yes, O slaves of Allah do take medicine, for Allah has not placed a disease but also placed a cure for it.” Or, he said, “A medicine for it”, “except for one disease. “They asked, ‘O Messenger of Allah (SAW), what is it”? He said, “Old age.”
