Narrated from Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him), he says: Among the judgments of the Messenger of Allah (peace and blessings be upon him) are these, (in this hadith he mentioned several judgments, among them were these two): The Messenger of Allah (peace and blessings be upon him) decided among the people of Madinah that no one should be prevented from the surplus or collected water of wells, and among the villagers he decided that surplus water should not be withheld with the intention of preventing others from the surplus grass. And when irrigating date palms with water flowing in the canals, the upper land should be irrigated before the lower land in such a way that the water reaches up to the ankles, then it should be released to the adjacent lower land, and in the same manner the water should be passed forward, until the gardens end or the water runs out.
