God says
Those who are bent on denying the truth and paid no heed to the Apostle will on that Day [of Resurrection] wish that earth would swallow them: …Q.4:41
But as for him who, after guidance has been manifested to him, cuts himself off from the Apostle and follows a path other than that of the believers -- him shall We leave unto that which he himself has chosen*, and shall cause him to endure hell: and how evil a journey’s end. -- Q.4:115
*a stress on man’s freedom of choice.
Now whenever God and His Apostle have decided a matter,* it is not for a believing man or a believing woman to claim freedom of choice insofar as they themselves are concerned: for he who [thus] rebels against God and His Apostle has already, most obviously, gone astray. -- Q.33:36
* I.e., Whenever a specific law has been formulated as such in the Quran or in an injunction promulgated by the Prophet.
