Musannaf Ibn Abi Shayba 27:94

Abu Mu'awiyah narrated to us, from al-A'mash, from Abu Sufyan, from Anas, who said: Gabriel came to the Prophet, may Allah bless him and grant him peace, while he was sitting and sad, for some of the people of Mecca had struck him. He said: "What is the matter with you?" He replied: "These and those have done [this] to me." He said: "Would you like me to show you a sign?" He said: "Yes." So he looked at a tree behind the valley and said: "Call that tree." So he called it, and it came walking until it stood before him. Then he said to it: "Return." So it returned until it went back to its place. Then the Prophet, may Allah bless him and grant him peace, said: "It is enough for me, it is enough for me."
