[1] This Hadith means that if one has a well near which there is a pasture and there is no other source of water in the area, one should not withhold the water from the sheep grazing there, for that would make it impossible for the sheep to graze there as they would be in great need of water after grazing. So, to withhold the water means to prevent sheep from grazing as well. (Fath Al-Bári Vol. 5, Page 429).
