Sayyiduna Uthman bin Abi al-As (may Allah be pleased with him) narrates: I complained to the Prophet (peace and blessings be upon him) about forgetting the Qur'an. The Prophet (peace and blessings be upon him) struck my chest with his blessed hand and said: "O Shaytan! Get out of the chest of Uthman!" The narrator says: After that, whatever verse I tried to remember, I did not forget any of it.
Al-Tabarani recorded it; its chain contains a narrator, Uthman bin Bishr, and I do not know him; the remaining narrators of this report are thiqat (trustworthy). (Allamah al-Haythami says:) I say: Some hadiths related to this meaning have come in various places throughout the book.
