The 19th century is known as a period whereas the military, economic and cultural invasions of the Western States reached its zenith. Muslim thinkers have anticipated solutions to the struggle against the West and they also have submitted a serious attempt in the cultural field throughout the time. This struggle took place more intensely in the Balkans, which was particularly adjacent to the Christian World. Hacı Abdullah Petricî who was an Ottoman scholar from Balkans and he became famous for his critiques of Christianity – in a period when the Christian world attacked the Muslim geography. He composed the Arabic and Ottoman epistles by suggesting that the Torah and the Gospels had been falsified, besides he wrote to prove the protected status of the Qur'an. According to Petrici, to explain that the Qur'an is protected from all falsehoods and omissions, it is at least as important to explain that the original text of the previous holy books could not be preserved. Petricî explained the protection of the Qur'an by providing evidence from the Qur'an itself and revealed the intellectual and historical shreds of evidence in this regard. In this article, Petrici’s views on that subject have been preceded, Latinized and published in the context of his epistle named Risâle fî Reddi’r-Revâfız ve İsbâti Temâmiyyeti Kur’ân-ı ‘Azîmi’ş-Şân which the relevant academic circles will be informed for the first time about.
