1Sahil B = ""The Quran, as a holy and revealed scripture, repeatedly reminds Muslims that what they are hearing is not a new message but the “confirmation of previous scriptures” (12:111). In fact, the Quran proposes the unprecedented notion that all revealed scriptures are derived from a single concealed book in heaven called the Umm al-Kitab, or “Mother of Books” (13:9). That means that as far as Muhammad understood, the Torah, the Gospels, and the Quran must be read as a single, cohesive narrative about humanity’s relationship to God, in which the prophetic consciousness of one prophet is passed spiritually to the next: from Adam to Muhammad. For this reason, the Quran advises Muslims to say to the Jews and Christians:We believe in God, and in that which has been revealed to us, which is thatwhich was revealed to Abraham and Ismail andJacob and the tribes [of Israel], as well as that which the Lordrevealed to Moses and to Jesus and to all the other Prophets.We make no distinction between any of them;we submit ourselves to God. (3:84)Of course, Muslims believe that the Quran is the final revelation in this sequence of scriptures, just as they believe Muhammad to be “the Seal of the Prophets.” But the Quran never claims to annul the previous scriptures, only to complete them. And while the notion of one scripture giving authenticity to others is, to say the least, a remarkable event in the history of religions, the concept of the Umm al-Kitab may indicate an even more profound principle.As the Quran suggests over and over again, and as the Constitution of Medina explicitly affirms, Muhammad may have understood the concept of the Umm al-Kitab to mean not only that the Jews, Christians, and Muslims shared a single divine scripture but also that they constituted a single divine Ummah. As far as Muhammad was concerned, the Jews and the Christians were “People of the Book” (ahl al-Kitab), spiritual cousins who, as opposed to the pagans and polytheists of Arabia, worshipped the sameGod, read the same scriptures, and shared the same moral values as his Muslim community. Although each faith comprised its own distinct religious community (its own individual Ummah), together they formed one united Ummah, an extraordinary idea that Mohammed Bamyeh calls “monotheistic pluralism.” Thus, the Quran promises that “all those who believe—the Jews, the Sabians, the Christians—anyone who believes in God and the Last Days, and who does good deeds, will have nothing to fear or regret” (5:69; emphasis added)."-No god but God, Reza Aslan "
