With the same chain, it is transmitted from Sayyiduna Murrah (may Allah be pleased with him) that he narrates: "I was travelling with the Prophet (peace and blessings be upon him). He camped at a place and said to me: 'Go to those two small trees and say to them: The Messenger of Allah commands you both to come together.' I came to those two trees and said this to them, and one of them moved towards the other, and the two of them came together. The Prophet (peace and blessings be upon him) went and relieved himself behind the cover of the two of them. Then each of them (the trees) went back to its place."
Ahmad also recorded it.
