According to search-discovered classical Islamic scholarship, the Quranic statement in Surah At-Takwir, 'Nor is it the word of an accursed Satan' (81:25), serves as a definitive refutation of any claims attributing the divine revelation to a satanic source. Tafsir authorities such as Ibn Kathir and Al-Tabari explain this verse was revealed to counter the accusations of the Quraysh, who likened the Prophet's message to the utterances of soothsayers or poets supposedly inspired by jinn. The verse powerfully affirms that the Quran is the protected, sacred speech of Allah, conveyed by the trustworthy angel Jibril. The term 'rajim' (accursed or stoned) signifies a devil who is cast out and barred from accessing the celestial realm where revelation originates. This concept is central to the Islamic doctrine of the Preservation of Revelation (Hifz al-Wahy), which guarantees the Quran's purity from any corruption or interference. The synthesis of scholarly commentary on this verse establishes an unequivocal theological principle: the Quran's message of pure monotheism, morality, and divine guidance is fundamentally antithetical to the nature and objectives of any satanic force.
