Narrated Umm Habibah bint Al-'Irbad: From her father: "On the day of Khaibar, the Messenger of Allah (ﷺ) prohibited eating the meat of every predator that has canine teeth, the meat of every bird that has talons, the meat of the domestic donkey, the Mujath-thamah, the Khalisah, and from having relations with a pregnant slave until she gives birth to what is in her womb." Muhammad bin Yahya said: "Abu 'Asim was asked about Mujath-thamah and he said: "To ensnare a bird or something and then shoot it." He was asked about Khalisah, so he said: "(Prey) that a man finds with a wolf or a predator, then he takes it from him but it dies in his hand before it can be slaughtered."
