Jabir said that when God’s messenger was asked whether ablution might be performed with water which asses had left, he replied, “Yes, and with what all beasts of prey leave.”
Yahya b. Abd ar-Rahman said that ‘Umar went out with a party of riders among whom was ‘Amr b al-‘As. When they came to a cistern and ‘Amr asked its owner whether beasts of prey came down to it, ‘Umar said, “Don't tell us, owner of the cistern, for we go down to what beasts of prey leave, and they go down to what we leave.”
Malik transmitted it and Razin made an addition saying that some transmitters add to ‘Umar’s words that he said he had heard God’s messenger say, “They have in their bellies what they have taken, and what remains is pure for us and drinkable.”
Dawud b. Salih b. Dinar quoted his mother as saying that her mistress sent her to ‘A'isha with some hari a. She said that she found her praying and that she signed to her to lay it down. A cat came and ate some of it, but when ‘A'isha finished praying she ate from the place where the cat had eaten, stating that God’s messenger had said, “It is not unclean; it is one of those who go round among you adding that she had seen God’s messenger using water it had left to perform his ablution.
