This is the first article in the chapter Enormities from the classical manual on Sharia called Reliance of the Traveller. I will post them one by one in the order they are given in the book, not leaving out anything.
p1.0 ASCRIBING ASSOCIATES TO ALLAH MOST HIGH (SHIRK)
p1. 1 Ascribing associates to Allah Most High means to hold that Allah has an equal, whereas He has created you, and to worship another with Him, whether it be a stone, human, sun, moon, prophet, sheikh, jinn, star, angel, or other.
p1.2 Allah Most High says:
(1) “Allah does not forgive that any should be associated with Him, but forgives what is other than that to whomever He wills” (Koran 4:48).
(2) “Surely, whoever ascribes associates to Allah, Allah has forbidden him paradise, and his refuge is hell” (Koran 5:72).
(3) “Of a certainty, worshipping others with Allah is a tremendous injustice” (Koran 31:13).
p1.3 The Koranic verses concerning this are very numerous, it being absolutely certain that whoever ascribes associates to Allah and dies in such a state is one of hell’s inhabitants, just as whoever believes in Allah and dies as a believer is one of the inhabitants of paradise, even if he should be punished first.
There is no information here how this enormity is to be punished under Sharia. What is the punishment for it in today’s Muslim countries which apply Sharia, like Saudi Arabia, Iran, Pakistan? Do they differ between each other? Do they differ from how Sharia was applied in the past?
