What is the ruling on the residual drink of beasts of prey and other specific animals, such as the domestic donkey and the mule?
Chapter on what purification is achieved with regarding water
Al-Mughni
Book of Purification
Primary text
The second category of impure animals involves all beasts of prey, excluding felines and smaller animals, as well as birds of prey, the domestic donkey, and the mule. A narration from Ahmad states their residual drink is impure, and if no other water is available, dry ablution (Tayammum) must be performed instead, leaving the residual drink. A narration from Ibn 'Umar stated dislike for the donkey's residual drink, aligning with the views of Al-Hasan, Ibn Sirin, Al-Sha'bi, Al-Awza'i, Hammad, and Ishaq.

A narration from Ahmad regarding the mule and donkey suggests that if only their residual drink is available, dry ablution (Tayammum) should be performed with it, which implies purity, as impure water cannot be used for purification. Conversely, the view permitting use implies purity. Some scholars granted permission based on the hadith about communal watering holes used by wild beasts, suggesting the residual drink is pure, like the permitted animals, as it is a usable animal without necessity. The argument for impurity rests on the Prophet's statement regarding water quantities (two qullahs) and the statement regarding donkeys at Khaybar being 'rijs' (filth), interpreted as forbidden meat, or that beasts of prey commonly consume carcasses.
