To proceed:
The Council of the Islamic Fiqh Academy of the Muslim World League, in its tenth session convened in Mecca from Saturday 24 Safar 1408 AH (17 October 1987 CE) until Wednesday 28 Safar 1408 AH (21 October 1987 CE), after examining the question of slaughtering edible animals by means of electric stunning and deliberating upon it, resolved the following:
First: If an edible animal is stunned with an electric current and is then slaughtered—or otherwise ritually dispatched—while life still remains in it, the act constitutes a valid slaughter and its meat is lawful to eat, by virtue of the general meaning of Allah’s words: “Prohibited to you are carrion, blood, the flesh of swine, that over which a name other than Allah’s has been invoked, the strangled, the beaten to death, the fallen, the gored, and that partially eaten by predators—except what you are able to slaughter [before it dies]” (al-Ma’idah 5:3).
Second: If the soul of the animal subjected to electric stunning departs before it is slaughtered, it is carrion and eating it is forbidden, in accord with the same general statement: “Carrion has been forbidden to you.”
Third: Stunning an animal with a high-voltage current amounts to torturing it before slaughter, and Islam forbids such treatment, commanding mercy and compassion toward animals. The Prophet ﷺ said, “Allah has prescribed excellence in everything. So when you kill, kill well; and when you slaughter, slaughter well. Let one of you sharpen his blade and spare suffering to his sacrifice.” (Related by Muslim).
Fourth: If the electric current is low-voltage and mild so that the animal is not tormented, and there is a benefit—such as reducing the pain of slaughter or calming its struggle—then there is no legal objection, out of consideration for that benefit. Allah knows best.
May abundant blessings and peace be upon our master Muhammad, his family, and his companions, and all praise belongs to Allah, Lord of the worlds.
