Yahya bin 'Ammara يحيى بن عمارة بن أبي حسن الأنصاري · The Office of the Judge (Kitab Al-Aqdiyah)

'Amr bin Shu'aib on his father's authority said that his grandfather told that the Messenger of Allah (ﷺ) decided regarding the stream al-Mahzur that its water should be held back till it reached the ankles, and that the upper waters should then be allowed to flow to the lower.
