The document discusses the work 'Izhar-ul-Haq' by Rahmatullah Kairanvi, which critiques the authenticity of the Bible and its texts, addressing contradictions and errors, and refuting the concept of the Trinity. Kairanvi's study was a response to a Christian offensive against Islam during British rule in India, aiming to establish that the Bible is not a directly revealed text. The text also outlines the books of the Old and New Testaments, their divisions, and various interpretations and controversies surrounding them.
