Hazrat Aisha (may Allah be pleased with her) narrates that indeed the Noble Prophet (peace and blessings be upon him) used to supplicate for the sick in this way: "O Lord of the people! Remove the suffering. Grant healing, for You are the Healer. There is no healing except Your healing. Grant such a healing that no illness remains." Hazrat Sufyan says that I mentioned this hadith before Hazrat Mansur, so he also narrated this hadith with the aforementioned chain of transmission.
