Getting rid of a sick animal whose illness is not expected to end

Question:
We say: Honorable Shaykh, may Allah grant you success. If a person has an animal that becomes ill with an illness that is not expected to end, and there is no longer any benefit in it, is it permissible for him to get rid of it? And is it permissible for him to take it out and leave it to its own devices?

Answer:
No, it is not permissible for him to take it out and leave it to its own devices. There is no harm if someone comes and feeds it. As for slaughtering it to get rid of it, that is not permissible. It is not permissible to slaughter an animal except for eating it, if it is edible. If it is not edible, then he must either spend on it or let it go out to eat from the land, or someone else should feed it and treat it kindly. Yes.
