Sahih al-Bukhari 2353
Sahih al-Bukhari · Book 42: Distribution of Water · Whoever said, “The owner of the water has the right to drink till he is satisfied, as the Prophet ﷺ said, ‘Superfluous water should not be withheld from others.’”
Narrated Abu Huraira:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنْ أَبِي الزِّنَادِ ، عَنِ الأَعْرَجِ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يُمْنَعُ فَضْلُ الْمَاءِ لِيُمْنَعَ بِهِ الْكَلأُ " .
Allah's Messenger (ﷺ) said, "Do not withhold the superfluous water, for that will prevent people from grazing their cattle."
