According to search-discovered classical Islamic scholarship, the concept that divine revelation 'leads to the Straight Path' is a cornerstone of faith, explicitly detailed in Surah Ash-Shura, verses 42:52-53. Tafsir by authorities such as Ibn Kathir and al-Tabari clarifies that Allah sent the Quran—described as a 'spirit' (Ruhan) and a 'light' (Nuran)—to the Prophet Muhammad to guide humanity. Prior to this revelation, the Prophet himself was not aware of the specifics of the Book or faith. This divine light serves as the means by which Allah guides His servants. The synthesis of these verses shows a powerful theological sequence: verse 52 affirms that the Prophet, through this revelation, is indeed guiding to a 'Straight Path' (ṣirāṭin mustaqīmin). Verse 53 then defines this path with ultimate authority as 'the Path of Allah' (ṣirāṭi Allāh), the Creator to Whom all things belong and to Whom all matters return. This establishes that the guidance brought by the Prophet is not his own, but a direct conduit to the divine way of life ordained by the Sovereign of the heavens and the earth.
