Qur’anic Orthography Miracle
Many words in the noble Quranic codex were written in a manner unfamiliar to the Arabs before, such as one spelling of mercy appearing instead of its familiar spelling, and likewise blessing appearing in two different spellings, along with many other examples. The enemies of the religion imagined that this variation in letter form was evidence of distortion in the Quranic codex because it contradicted the Arabic language rules they were accustomed to. All Islamic scholars, whether scholars of religious law or scholars of the Arabic language, were perplexed in trying to find a convincing answer to this problem, and they failed completely. Then this book appeared to represent the complete and detailed answer proving that the variation in letter forms from what is familiar is in fact a true miracle established scientifically.
