Izhar ul-Haqq

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.

The book was originally written in Arabic in 1864, this six-volume book was later translated (or summarized) into English, Turkish, Urdu and Bengali. 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.
