Also, the Qur'an is a founder; it is the basis of the Clear Religion, and the foundation of the world of Islam. It changed human social life, and is the answer to the repeated questions of its various classes. Repetition is necessary for a founder in order to establish things. Repetition is necessary to corroborate them. Confirmation, verification and repetition are necessary to emphasize them.

Also, it speaks of such mighty matters and minute truths that numerous repetitions are necessary in different forms in order to establish them in everyone's hearts. Nevertheless, they are apparently repetitions, but in reality every verse has numerous meanings, numerous benefits, and many aspects and levels. In each place they are mentioned with a different meaning, for different benefits and purposes.

Also, the Qur'an's being unspecific and concise in certain matters to do with cosmos is a flash of miraculousness for the purpose of guidance. It cannot be the target of criticism and is not a fault, like some atheists imagine.

If you ask: "Why does the All-Wise Qur'an not speak of beings in the same way as philosophy and science? It leaves some matters in brief form, and some it speaks of in a simple and superficial way that is easy in the general view, does not wound general feelings, and does not weary or tax the minds of ordinary people.

But philosophy and science look at beings for themselves, and address scientists in particular. In which case, since the All-Wise Qur'an makes beings evidences and proofs, the evidence has to be superficial so that it will be quickly understood in the general view. And since the Qur'an of Guidance addresses all classes of men, the ordinary people, which form the most numerous class, want guidance which is concise with unnecessary things being vague, and which brings subtle things close with comparisons, and which does not change things which in their superficial view are obvious into an unnecessary or even harmful form, lest it causes them to fall into error.

For example, it says about the sun: "The sun is a revolving lamp or lantern." For it does not speak of the sun for itself and its nature, but because it is a sort of mainspring of an order and centre of a system, and order and system are mirrors of the Maker's skill. It says:
