The miracle of the Qur'an and the prophetic eloquence

In this book, the scholar and thinker Mustafa Sadiq Al-Rafi'i devotes his discussion to the miracle of the Holy Qur'an and the prophetic eloquence, and he limited what he dealt with to the matter of language in its setting, arrangement, and purpose, to what is related to one of these aspects, or is a principle in it, a cause of it, or a means to it, This is, in fact, the face of the strange miracle that permeated the linguistic spirit of those eloquent Arabs.
Al-Rafi'i says in the introduction to his book: It is no secret to you that this in its entirety is as if it were a chapter in the philosophy of language. It follows what we have presented about its matter, completes what we left there, and conveys the statement about its virtues and secrets, so some of that is completely superior to others. Because the language there is vocabulary and the language here is constructions, and no man with knowledge of Arabic speech and its craftsmanship will dispute or doubt that the Qur'an is the miracle of this Arabic in the eloquence of its structure and the consistency of its conditions and secrets. Hence, the material of communication was in the pattern of composition between this part and the one before it.
