Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Muhammad bin Yahya that Walid bin Walid bin Mughirah Makhzumi complained to the Messenger of Allah, peace and blessings be upon him, about the thoughts that would come to him. So the Prophet, peace and blessings be upon him, said: "When you come to your bed, say this: I seek refuge in the perfect words of Allah from His anger and punishment, and from the evil of His servants, and from the evil suggestions of devils, and from their coming near me. By the One in Whose hand is my soul, nothing will harm you until morning."
