If a person has a sick animal and does not want to eat it, is it in accordance with the Sunnah to slaughter it, or to let it die without ritual slaughter?

The questioner : A questioner says: If a person has a sick animal and does not want to eat it, is it in accordance with the Sunnah to slaughter it, or to leave it without ritual slaughter? It has become common among people, or it is widespread, that they say, "Relieve it by slaughtering it."

The Shaykh : As for if the animal belongs to the person himself, if it becomes ill with an illness from which recovery is not expected and it is not possible to benefit from it afterwards, he may kill it. This is because keeping it would bring him sin due to not spending on it, and if he spends on it while no benefit is expected from it, either in the present or in the future, the spending on it becomes a waste of money. We are prohibited from wasting money. So if he kills it, he is relieved of it, and there is no blame on him for that. As for if the animal does not belong to him, such as if a person passes by an animal in the desert and it is in pain from an illness, he does not kill it; he leaves it to Allah the Exalted, because this is not part of his action, and he is not responsible for this animal. Yes.
