Sayyiduna Uthman Ghani (may Allah be pleased with him) narrates: I fell ill, and the Prophet (peace and blessings be upon him) came to visit me. He performed ruqyah on me, reciting this: "Seeking blessing by the name of Allah Almighty, the Most Gracious, the Most Merciful, I place you under the protection of Allah, the One, the Self-Sufficient, who has not begotten anyone and was not begotten, and to whom no one is equal, from the evil of everything that you feel (or find)." When the Prophet (peace and blessings be upon him) stood up, he said: "O Uthman, seek refuge by means of it! You will not seek refuge by means of anything (any other words) like it."
Abu Ya'la recorded it in al-Kabir from his teacher Musa bin Hayyan, whom I do not know. The remaining narrators of this report are the narrators of the Sahih.
