Musnad Ahmad 32:1466

Hassan ibn Musa narrated to us, Abu Hilal narrated to us, Qatadah narrated to us, from Anas ibn Malik, that there was a tree on the people's path that used to harm them. A man came to it and removed it from the people's path. He said: The Prophet, peace and blessings of Allah be upon him, said: "I have seen him moving about in its shade in Paradise."
