Themes of suspicion about divinity in Quran

Among most important factors that bring people into denial, there is one that gets them in hesitation and affliction, that is, ?doubt?. The human who can not get over this doubt is never able to have a complete belief. On the other hand, with its positive sense, it is possible to use doubt as a tool to attain the genuine belief. But is the doubt which disbelievers and deniers put forward from this kind that bring them to the belief? What are characteristics of their doubts? Otherwise, are they some insincere arguments resulting from darkness and stubborness?In this study, we try to look into and evaluate these kinds of doubt in the light of Quran. We have dealt with their doubts and argumants over God, Quran and revelation, prophecy and afterlife and resurrection seperately. Finally we have tried to find some replies to these doubts and arguments of theirs.
