According to search-discovered classical Islamic scholarship, the concept of distorting the meanings of revelations, known as 'Tahrif' (تحريف), refers to the deliberate alteration, misinterpretation, or concealment of divine scriptures. The Quran, in verses such as 4:46, 5:13, and 5:41, specifically attributes this act to certain groups among the People of the Book. Classical commentators like Ibn Kathir explain that this distortion took multiple forms, from verbal manipulation and twisting words with their tongues to mock the faith, to altering the text from its proper context. Al-Tabari and Al-Qurtubi often link these verses to historical incidents with some Jewish tribes of Madinah who would conceal or misrepresent parts of the Torah, particularly those concerning the description of Prophet Muhammad or specific legal rulings. Scholars have broadly categorized Tahrif into 'Tahrif al-Ma'na' (corruption of meaning), which many early scholars emphasized, and 'Tahrif al-Nass' (corruption of the text), which was argued more forcefully by later scholars like Ibn Hazm. The unified theme across these verses is that such distortion is a grave sin, stemming from disbelief and hardened hearts, and results in a divine curse and spiritual misguidance.
