According to search-discovered classical Islamic scholarship, the concept of the Quran's infallibility from fabrication, powerfully articulated in Surah Al-Haqqah (69:44-47), is a foundational tenet of Islamic belief. Ibn Kathir explains that this passage serves as God's ultimate testimony to the Prophet Muhammad's truthfulness. [3] The verses present a severe, hypothetical consequence: had the Prophet forged any sayings and ascribed them to God, his life artery would have been instantly severed. Al-Tabari's linguistic analysis confirms that the Arabic term 'taqawwul' specifically means to concoct or fabricate speech. This synthesis of scholarly interpretations across the verses establishes a crucial doctrine: the divine message is so sacred that it is divinely protected at the source of its transmission. This theological proof guarantees for Muslims that the Quran is the pure, unaltered Word of God, conveyed with perfect fidelity by His final messenger.
