Abu Qilabah (may Allah have mercy on him) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Do not cause harm to anyone through a wide well or a wide excavation."
Sa'id (may Allah have mercy on him) added: That is, a man digs next to another man in order to take away his water.
