Absolute Freedom of Religion
[18:29] Proclaim: “This is the truth from your Lord,” then whoever wills let him believe, and whoever wills let him disbelieve. We have prepared for the transgressors a fire that will completely surround them. When they scream for help, they will be given a liquid like concentrated acid that scalds the faces. What a miserable drink! What a miserable destiny!
[18:30] As for those who believe and lead a righteous life, we never fail to recompense those who work righteousness.
[18:31] They have deserved gardens of Eden wherein rivers flow. They will be adorned therein with bracelets of gold, and will wear clothes of green silk and velvet, and will rest on comfortable furnishings. What a wonderful reward; what a wonderful abode!
No Compulsion in Religion
[2:256] There shall be no compulsion in religion: the right way is now distinct from the wrong way. Anyone who denounces the devil and believes in GOD has grasped the strongest bond; one that never breaks. GOD is Hearer, Omniscient.
[109:0] In the name of God, Most Gracious, Most Merciful [109:1] Say, “O you disbelievers. [109:2] “I do not worship what you worship. [109:3] “Nor do you worship what I worship. [109:4] “Nor will I ever worship what you worship. [109:5] “Nor will you ever worship what I worship. [109:6] “To you is your religion, and to me is my religion.”
[6:107] Had GOD willed, they would not have worshiped idols. We did not appoint you as their guardian, nor are you their advocate.
How Terrible is Hell!*
[22:19] Here are two parties feuding with regard to their Lord. As for those who disbelieve, they will have clothes of fire tailored for them. Hellish liquid will be poured on top of their heads. [22:20] It will cause their insides to melt, as well as their skins. [22:21] They will be confined in iron pots. [22:22] Whenever they try to exit such misery, they will be forced back in: “Taste the agony of burning.”
*22:19-22 People who have insisted upon going to Hell will inevitably complain: ‘Had we known how bad this is, we would have behaved differently.’ They will be told that the horrors of Hell have been pointed out to them in the most graphic, though symbolic, terms. It should be noted that Heaven and Hell are almost invariably mentioned together in the Quran.
