Islam recognizes that no one religion holds a monopoly over salvation. The Holy Quran clearly supports this belief as it declares, “Surely, those who believe and the Jews and the Christians and the Sabians—whichever party from among these truly believes in God and the Last Day and does good deeds shall have their reward with their Lord, and no fear shall come upon them, nor shall they grieve” (2:63).
This verse demonstrates that it is not just Muslims who will receive the rewards of their good deeds. Jews, and Christians, and Sabians—those who are of non-Abrahamic religions—will all be rewarded for their good deeds and their faith. Indeed, it is impossible for Muslims to declare a monopoly on salvation when the Holy Quran clearly states that those of other religions who do good deeds will have no fear.
Islam recognizes that the right to decide who goes to heaven and who goes to hell is one that is exclusive to God. Human beings—Muslims or otherwise—cannot make this decision. Likewise, the Holy Quran states, “As to those who believe…verily, Allah will judge between them on the Day of Resurrection. Surely, Allah watches over all things” (22:18).
The Holy Quran is likewise clear that God’s grace and mercy are His most powerful attributes:
God replied, I will inflict My punishment on whom I will; but My mercy encompasses all things (7:157).
Therefore, Islam recognizes that ultimately, God’s mercy will encompass all human beings, regardless of their faith. Indeed, Islam teaches that if mercy were not one of the attributes of God, no one would be delivered.
Therefore, Islam rejects any type of a monopoly on salvation.
