Slaughter for other than Allah

Q: Is slaughter for other than Allah permissible? Because we have people who slaughter for a man named (Majla), and when we ask who Majla is, they say: He is a prophet from the prophets of Allah. Please inform us about this, may Allah reward you.

A: Slaughter for other than Allah is a great evil and major shirk (associating partners with Allah), whether it is for a prophet, a wali (close friend of Allah), a star, a jinn, an idol, or anything else; because Allah the Exalted says: [Al-An'am: 162 - 163] So He the Exalted informed that slaughter is for Allah just as prayer is for Allah. So if one slaughters for other than Allah, it is like one who prays for other than Allah, and it becomes shirk (associating partners with Allah) with Allah . And thus Allah says to His Prophet (peace and blessings be upon him): So pray to your Lord and sacrifice [Al-Kawthar: 1 - 2]. So prayer and sacrifice are two great acts of worship.
So whoever directs slaughter to the people of graves, or to the prophets, or to the stars, or to the idols, or to the jinn, or to the angels, has associated partners with Allah, just as if he prayed to them, or called upon them for aid, or made vows to them. All of this is shirk (associating partners with Allah) with Allah Mighty and Majestic. And Allah the Exalted says: [Al-Jinn: 18], and He says : [Adh-Dhariyat: 56], and He the Exalted says: [Al-Isra: 23].
So worship is the right of Allah, and slaughter is from worship, and thus calling for aid is from worship, and thus prayer is from worship. And it is established from the Messenger of Allah (peace and blessings be upon him) that he said: Narrated by Muslim in his Sahih from the hadith of Ali (may Allah be pleased with him) . So you must disapprove of these people, and teach them that this is major shirk (associating partners with Allah), and that it is obligatory for them to leave that, for they have no right to slaughter for other than Allah, just as they have no right to pray for other than Allah. And this is from the category of cooperating in righteousness and piety, and from the category of forbidding evil, and from the category of calling to Allah and making worship sincere for Him, and from the tawhid (the oneness of Allah) that must be for Him alone . And this is the duty of the people of knowledge, and the duty of the students of knowledge, and the duty of the imams of the Muslims, that they cooperate in righteousness and piety, and that they disapprove of shirk (associating partners with Allah) from whoever does it, until tawhid (the oneness of Allah) becomes manifest and until the causes of shirk (associating partners with Allah) are eliminated. We ask Allah for success and guidance for everyone.
