Abdul Aziz says: We went with Sayyiduna Thabit (may Allah be pleased with him) to Sayyiduna Anas bin Malik (may Allah be pleased with him). Sayyiduna Thabit (may Allah be pleased with him) said to him: I am ill. In response, Sayyiduna Anas (may Allah be pleased with him) said: Shall I not perform the ruqyah (spiritual healing) for you that Abu al-Qasim (peace and blessings be upon him) used to do? He said: Yes, please do. He said: Then recite this supplication: "O Allah! Lord of mankind! Remover of affliction! Grant healing, for You are the Healer. There is no healer except You. Grant such a healing that leaves behind no illness."
