Thus, repetition in the Qur'an looks to principles like these. Sometimes on one page, even, with regard to the requirements of the position and the need for explanation and the demands of eloquence, it expresses the truth of Divine unity perhaps twenty times explicitly and by implication. It does not cause boredom, but gives a power to it and inspires an eagerness. It has been explained in the Risale-i Nur with proofs how appropriate, fitting, and acceptable from the point of view of rhetoric are the repetitions in the Qur'an. The wisdom and meaning of the Meccan and Medinan Suras in the Qur'an of Miraculous Exposition being different in regard to eloquence, miraculousness, and detail and brevity is as follows:

In Mecca, the first line of those it was addressing and those opposed to it were the Qurayshi idolators and untaught tribesmen, so a powerful and elevated style in regard to rhetoric was necessary, and a miraculous, convincing, persuasive conciseness, and in order to establish it, repetition was required. Thus, in most of the Meccan Suras, repeating and expressing the pillars of belief and degrees in the affirmation of Divine unity with a most powerful, elevated, and miraculous conciseness, it proved so powerfully the first creation and the Resurrection, God and the hereafter, not only in a single page, verse, sentence or word, but sometimes in a letter, through grammatical devices like inverting the words or sentences, making a word indefinite, and omissions and inclusions, that the geniuses and leaders of the science of rhetoric met it with wonder. The Risale-i Nur, and the Twenty-Fifth Word and its Addenda in particular, which prove in summary forty aspects of the Qur'an's miraculousness, and the Qur'anic commentary, Isharat al-I'jaz, from the Arabic Risale-i Nur, which in wondrous fashion proves the aspect of the Qur'an's miraculousness ,in its word-order, have demonstrated in fact that in the Meccan Suras and verses are the highest styles of eloquence and the most elevated, concise miraculousness.

As for the Medinan Suras and verses, since the first line of those they were addressing, who opposed them, were the People of the Book, such as the Jews and Christians who affirmed God's existence, what was required by eloquence and guidance and for the discussion to correspond to the situation, was not explanation of the high principles of religion and pillars of belief in a simple, clear, and detailed style, but the explanation of particular matters of the Shari'a and its injunctions, which were the cause of dispute, and the origins and causes of secondary matters and general laws. Thus, in the Medinan Suras and verses, through explanations in a detailed, clear, simple style, in the matchless manner of exposition peculiar to the Qur'an, it mostly mentions within those particular secondary matters, a powerful and elevated summary; a conclusion and proof, a sentence relating to Divine unity, belief, or the hereafter which makes the particular matter of the Shari'a universal and ensures that it conforms to belief in God. It illuminates the passage, and elevates it. The Risale-i Nur has proved the qualities and fine points and elevated eloquence in the summaries and conclusions, which express Divine unity and the hereafter, and come mostly at the end of verses, like:
