From Iyas bin 'Abd al-Muzani who said: "The Prophet ﷺ prohibited selling water." [He said:] There are narrations on this topic from Jabir, Buhaisah from her father, Abu Hurairah, 'Aishah, Anas and 'Abdullah bin 'Amr.  

نَهَى النَّبِيُّ ﷺ عَنْ بَيْعِ الْمَاءِ قَالَ وَفِي الْبَابِ عَنْ جَابِرٍ وَبُهَيْسَةَ عَنْ أَبِيهَا وَأَبِي هُرَيْرَةَ وَعَائِشَةَ وَأَنَسٍ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو  

That the Prophet ﷺ said: "Do not withhold surplus water so that it is prevented from the pasture."  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ يُمْنَعُ فَضْلُ الْمَاءِ لِيُمْنَعَ بِهِ الْكَلأُ
