According to the consensus of classical Islamic scholarship, the principle of believing 'in all revelations'—known in Arabic as Al-Iman bil-Kutub—is a foundational and non-negotiable pillar of Islamic faith (Iman). As articulated in key Quranic verses like 2:136 and 2:285, this concept requires Muslims to affirm the divine origin of all authentic scriptures revealed by God throughout history, including the Torah (Tawrat) given to Moses, the Psalms (Zabur) to David, and the Gospel (Injil) to Jesus. Tafsir Ibn Kathir explains that this belief signifies an acceptance of the universal, unbroken chain of divine guidance. The critical clause, 'we make no distinction between any of them,' is interpreted by scholars like Maududi to mean that one cannot selectively believe in one prophet while rejecting another, as doing so invalidates belief in the divine source itself. While affirming the original sanctity of these books, Islamic theology holds that only the Quran, the final revelation to Prophet Muhammad, remains perfectly preserved and serves as the ultimate, superseding guide for humanity.
