Kairanawi wrote books in Arabic, Persian and Urdu.
Izhar ul-Haq (Truth Revealed) Written originally in Arabic, the book
Izhar ul-Haqq in six volumes was translated later into Urdu, and from Urdu into a summarized English version published by Ta-Ha. The book aims to respond to Christian criticism of Islam. It is the first Muslim book to use Western scholarly works in order to ascertain the errors and contradictions of the Bible. The doctrine of Trinity is purportedly contested using biblical, Christian and other sources.
Christine Schirrmacher, a German scholar of Islamic Studies, states in an article on the Pfander-Kairanawi debate: "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." ==The Madrasa Sawlatia==
