Musannaf Ibn Abi Shayba 23:165

Waki' narrated to us, he said: Al-A'mash narrated to us, from Abu Sufyan, from Jabir, who said: A man came to the Prophet, may God bless him and grant him peace, and said: "O Messenger of God, I saw in a dream as if my head was cut off." The Prophet, may God bless him and grant him peace, laughed and said: "If the devil plays with one of you in his sleep, then do not narrate it to the people."
