Silsilat al-Ahadith al-Sahihah

Lady Aisha (may Allah be pleased with her) says: The Messenger of Allah (peace and blessings of Allah be upon him) used to perform ruqyah (spiritual healing) with these words: "O Allah! Lord of the people! Remove the suffering, grant healing, You are the Healer, there is no healing except Your healing, grant such a healing that leaves behind no illness." When the illness of the Prophet (peace and blessings of Allah be upon him) increased during his final sickness, I would take his hand and pass it over his body and recite these words, but he withdrew his hand and began to supplicate: "O Allah! Forgive me and join me with the Highest Companion." Lady Aisha (may Allah be pleased with her) says that these were the last words I heard from the tongue of the Prophet (peace and blessings of Allah be upon him).
