Abu Dharr said that the Prophet went out in winter time when the leaves were falling, and took two branches of a tree whose leaves began to fall. He then addressed Abu Dharr who replied, “At your service, Messenger of God.” He said, “A Muslim observes prayer for God’s sake and his sins fall from him as these leaves fall from this tree.” Ahmad transmitted it.
