According to search-discovered classical Islamic scholarship, the principle of addressing mutual religious invalidation is powerfully articulated in Surah Al-Baqarah, verse 113. Tafsir al-Tabari, citing Ibn Abbas, identifies the historical context as a dispute between the Jews and Christians of Najran in the Prophet's presence, where each party completely negated the religious foundation of the other. Ibn Kathir elaborates that this verse is a divine critique of such baseless sectarian arrogance, especially poignant because both groups 'recite the Scripture,' which should lead to mutual recognition of prophetic lineage, not total dismissal. The core of the verse, as unanimously interpreted by scholars, lies in its conclusion: 'Allah will judge between them on the Day of Resurrection concerning that over which they used to differ.' This establishes a fundamental Islamic tenet for interfaith relations: humans are not the final arbiters of theological truth claims between faith communities. The verse redirects the focus from worldly disputes to divine justice, promoting a stance of humility and respect, and serving as a timeless warning against religious prejudice.
