I n S h o r t : The All-Wise Qur’an demonstrates its miraculousness to forty different classes and groups of people, or it indicates to the existence of its miraculousness. It neglects no one. Even for those who can comprehend only what their eyes see and who have no ear to hear with, no heart to feel with, and no knowledge to judge with, the Qur’an alludes to its miraculousness in a fashion.(384) It is like this:

In the Qur’an of Miraculous Exposition handwritten by the calligrapher Hafiz Osman and later printed, many of the words look to one another. For example, if a needle is passed through the word “dog” in the phrase “they were seven, the dog being the eighth” in Sura al-Kahf (18:22) and through the underlying pages, with a slight deviation it will go through the word “Qitmir” in Sura al-Fatir (35:13), thus establishing the dog’s name. In a similar way, the words “they will be all brought before us” (muhdarun/-in) occur twice in Sura Ya. Sin.

-----------------------------------------
(384) Here the mention of the aspect of its miraculousness directed to those without ear, heart and knowledge, and who see only with their eyes, is extremely concise, abbreviated, and even deficient. But it has been demonstrated most clearly and brilliantly in the Twenty-Ninth and Thirtieth Letters,* so that even the blind can see it. We have had written a copy of the Qur’an which shows this aspect of miraculousness, which, God willing, will be published, then everyone will be able to see it.
*The Thirtieth Letter had been planned and intended, but it gave up its place to Isharat al-I‘jaz (Signs of Miraculousness), while itself never materialized.
