It is narrated from Hazrat Aisha (may Allah be pleased with her) that when the Prophet (peace and blessings be upon him) would perform ruqyah on any of his family members, he would pass his right hand over them and recite this supplication: "O Lord of the people! Remove this pain. Grant him/her healing, for You are the Healer. There is no healing except Your healing. Grant such a healing that leaves no trace of illness."
