Euthanasia for animals may be considered permissible in cases where the animal is suffering from a chronic and serious illness, is unable to fulfill its basic needs due to physical problems, and there is no possibility of treatment. Based on expert opinions, if all possible treatments have failed and the animal is enduring excessive pain, euthanasia can be applied to prevent further suffering.
Historically, scholars from schools like the Hanafi and Maliki, as well as contemporary scholars and fatwa councils, have recognized such justifications as valid reasons for ending an animal’s life humanely.
