Yahya bin Ja'dah (may Allah have mercy on him) said that a man in Madinah wanted to place his beams on his neighbour's wall without his permission, and the neighbour prevented him. Then some of the Ansar related that the Messenger of Allah (peace and blessings be upon him) had "forbidden doing that", and so he was compelled (to allow it).
