Narrated Aisha (may Allah be pleased with her): When the Messenger of Allah (peace and blessings of Allah be upon him) would visit a sick person or a sick person was brought to him, he would make this supplication: "O Lord of the people! Remove the disease, O Sustainer of mankind! Grant cure, for You are the Healer. There is no cure except Your cure, grant such a cure that leaves no trace of illness."
