Musannaf Ibn Abi Shayba 23:166

Muhammad ibn Abd Allah al-Asadi narrated to us, from Umar ibn Sa'id ibn Abi al-Husayn, who said: Ata ibn Abi Rabah narrated to me, from Abu Hurayrah, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "I saw in a dream as if my head was struck, and I saw it with this hand of mine." He said: The Messenger of Allah, may Allah bless him and grant him peace, said to him: "Satan intends to frighten one of you, then he goes and tells the people."
