Umm al-Mu’minin Aisha (may Allah be pleased with her) says that whenever the Messenger of Allah (peace and blessings be upon him) would visit a sick person or a sick person was brought to him (the narrator is unsure), he (peace and blessings be upon him) would recite this supplication:“Lord of the worlds! Remove the illness of the people and grant healing. There is no healer except You. You are the Healer. Grant such a healing that no illness remains.”
