Narrated Thalabah ibn Abu Malik: Thalabah heard his elders say that a man from the Quraysh had his share with Banu Qurayzah (in water). He brought the dispute to the Messenger of Allah ﷺ about al-Mahzur, a stream whose water they shared together. The Messenger of Allah ﷺ then decided that when water reached the ankles waters should not be held back to flow to the lower.
