Such water is also considered pure, based on the hadith of Jabir in which the Messenger of Allah was asked about making ablution with drinking water left by donkeys. The Prophet, upon whom be peace, answered, “Yes, and from the drinking water left by any of the beasts of prey.” This hadith was related by ash-Shaifi, ad-Daraqutni and al-Baihaqi who said, “When its different chains are put together they become strong.” It has also been related from Ibn ‘Umar that the Messenger of Allah went out at night while he was on a journey. He passed by a man who was sitting by a pond. Said ‘Umar, “Did a beast of prey drink from your pond tonight?” The Messenger of Allah told him, “O owner of the pond, do not inform him. It is not necessary, for him (the beast of prey) is what he carried in his stomach and for us is what he left, water to be used for drinking and purifying.” This is related by ad-Daraqutni. Yahya ibn Sa’eed reported that once ‘Umar was among a group that included ‘Amr ibn al-‘Aas and, when they came upon a pond, ‘Amr said, “O owner of the pond, have the beasts of prey discovered your pond?” ‘Umar said, “Do not inform us, since the people drink after the wild beasts and the wild beasts after the people.” This is related by Malik in al-Muwatta.
