حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا الْمُثَنَّى بْنُ سَعِيدٍ، حَدَّثَنَا قَتَادَةُ، عَنْ بُشَيْرِ بْنِ كَعْبٍ الْعَدَوِيِّ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا تَدَارَأْتُمْ فِي طَرِيقٍ فَاجْعَلُوهُ سَبْعَةَ أَذْرُعٍ ‏"‏ ‏.‏
Translation
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 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.
