Q: Is it permissible to slaughter for other than Allah? People here slaughter animals for a person named Magly. When we ask them about him, they say he is a prophet of Allah. Please, advise. May Allah bless you!
A: Slaughtering for other than Allah (Exalted be He) is an abominable act and one of major Shirk (associating others with Allah in His Divinity or worship), whether it is made for a prophet, Waliy (pious person), planet, jinni (creature created from fire), idol, or other than that, for Allah (Glorified be He) says:
Say (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ): "Verily, my Salât (prayer), my sacrifice, my living, and my dying are for Allâh, the Lord of the 'Alamîn (mankind, jinn and all that exists). "He has no partner. And of this I have been commanded, and I am the first of the Muslims."
Verily, We have granted you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) AlKauthar (a river in Paradise). Therefore turn in prayer to your Lord and sacrifice (to Him only).
And the mosques are for Allâh (Alone): so invoke not anyone along with Allâh.
And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone).
And your Lord has decreed that you worship none but Him.
Allah has cursed the one who slaughters for other than Him.
