Iẓhār al-Ḥaqq, (also spelled as : Izhar-ul-Haq) (Arabic: إظهار الحق) is a book by Rahmatullah Kairanawi.
Kairanwi had written this book in response to the allegations made by certain Christian missionaries against Islam and especially to counter the Mizan al-Haqq of Karl Gottlieb Pfander against Islam.
[6] Christine Schirrmacher describes the book: 'The Demonstration of the Truth' (izhâr al-haqq) served as a summary of all possible charges against Christianity and was therefore used after al-Kairânawî's death as a sort of encyclopaedia since al-Kairânawî extended the material of former polemicists like 'Ali Tabarî, Ibn Hazm or Ibn Taymiyya to a great extent.
[7]Kairanawi made use of Western Biblical criticism as well as theological works.
[7] Late Maulana Akbar Ali Khan of Darul Uloom Karachi translated the book into Urdu.
