4:93Whoever kills a believer deliberately, the penalty for him is Hell, where he will remain forever. And God will be angry with him, and will curse him, and will prepare for him a terrible punishment.

4:115Whoever makes a breach with the Messenger, after the guidance has become clear to him, and follows other than the path of the believers, We will direct him in the direction he has chosen, and commit him to Hell—what a terrible destination!
