The Office of the Judge (Kitab Al-Aqdiyah)
Dawud :: Book 24 : Hadith 3631
Narrated Tha'labah ibn AbuMalik:
Tha'labah heard his elders say that a man from the Quraysh had his share with Banu Qurayzah (in water). He brought the dispute to the Apostle of Allah (peace_be_upon_him) about al-Mahzur, a stream whose water they shared together. The Apostle of Allah (peace_be_upon_him) then decided that when water reached the ankles waters should not be held back to flow to the lower.
