Hadith 514320
Chapter 36: Judgements - كتاب الأقضية
وَحَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يُمْنَعُ فَضْلُ الْمَاءِ لِيُمْنَعَ بِهِ الْكَلأُ " .
Malik related to me from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "Excess water is not withheld in order to prevent herbage from growing."
