Is a person who goes to a sorcerer to bring him a girl so he can marry her, and then marries her, and then dies after this act, destined to Hellfire, abiding therein eternally?

Consulting sorcerers is one of the major sins. If a person deems it permissible, then he is an apostate disbeliever. The destiny of a disbeliever who dies upon disbelief is the Fire. However, if he repents, rectifies his deeds, and regrets, then Allah forgives all sins. This person must offer sincere and truthful repentance, and Allah accepts the repentance of those who repent and wipes away their sins.
