Musnad Ahmad 32:629

Hassan narrated to us, Abu Hilal narrated to us, Qatadah narrated to us, from Anas ibn Malik, who said: There was a tree on the people's path that was harming the people. A man came to it and removed it from the people's path. He said: The Prophet, may Allah bless him and grant him peace, said: "I have seen him moving about in its shade in Paradise."
