They ask thee what is lawful to them (as food). Say: lawful unto you are (all) things good and pure: and what ye have taught your trained hunting animals (to catch) in the manner directed to you by Allah: eat what they catch for you, but pronounce the name of Allah over it: and fear Allah; for Allah is swift in taking account. Al-Ma'idah 5:4 ⧉
Tafsir:
All those things which are considered clean and perfectly formed in the eyes of nature, and all those animals whose nature is compatible with human nature, are all legitimate and permissible for human consumption. This is subject to the condition that for any external reason they have not developed any defect from the viewpoint of health or in the light of the Islamic law. However, the human mind is not capable of properly applying this principle. Therefore, the principle has been set forth along with its correct application. Hunting by a trained hunting animal is permissible because he catches the hunted animals on behalf of his master. In other words, he has learnt man’s nature. Such an animal, so to say, has become a substitute for man.
