The False Claimants Who are Rescued from the Viewpoint of the Holy Quran

This writing is going to answer this question whether achieving prosperity and salvation in eternal world from the viewpoint of the Holy Quran is restricted to faithfulness and belief in the religion of truth? In other words, those who will prosper and rescue from adversity and punishment, are only among followers of the religion of truth or there is a possibility for the false claimants who are not believed in the religion of truth and have chosen the void path, to be rescued and prospered? Which verses of the Holy Quran indicate this possibility or lack of it, and in case of rescuing this group of people, which conditions have stated for them?   In order to answer these questions, after overviewing the history of this topic, among the followers of religions, the terms “unbelief” and “unbeliever” are examined in terminology of the Holy Quran and from the viewpoints of religious jurisprudents; then the statements of proponents and opponents are studied and their Quranic reasons are examined, and at the end dividing  the false claimants to three groups: “antagonist”, “culprit” and “defaulter”, the last group believably are known as those who will rescue.
