It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that he said: "Two men disputed over a date palm, so the Messenger of Allah (peace and blessings be upon him) cut one of its branches and found its length to be five cubits; then he (peace and blessings be upon him) made that (measurement) the tree's protected boundary (harim)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Amr bin Yahya (may Allah have mercy on him) except al-Darawardi (may Allah have mercy on him)."
