They offer so many teachings...

They offer so many teachings, educational instructions, knowledge and information for “H im who has a heart or lends ear and he is a witness” [^10] That bewilders man. The stories of the Qur'an, such as the stories of Adam, Moses, Abraham and other prophets (' a ) are repeatedly stated in order to show that this Book is neither a book of stories nor of history, but a book of journeying to Allah, a book of tawhīd , knowledge, admonitions and aphorisms.

In such matters repetition is required so as to fix them in the hard-hearted souls and to have effects as an admonition to them.

In other words, whoever wants to educate, teach, warn and bring good tidings, has to express his intentions in different styles and diverse ways, such as narrations and tales, or historical stories, and sometimes in quite an explicit way, and sometimes by way of allusion and indirect hints, symbols and examples, so that different souls and scattered hearts can each be benefited by them.

As this noble Book is intended for the happiness of all classes and the human race, and as the human species differ in the condition of their hearts, in their customs, behaviors, time and place, they cannot be attracted in the same way. Many of them may not be prepared to accept the instructions and the original matter in a direct, clear and explicit language, or to be affected by it.

They are to be approached in accordance with the construction of their brains in order to make them comprehend what is intended. Some others are not interested in stories, tales and histories, as they are in quest of the cores of the matters and the real aims. They cannot be taken on the same basis with the former ones. Many hearts are fit for being frightened and warned; other hearts are attracted by promises and hopes.

Consequently, this noble Book uses different methods, styles and ways for its invitation of the people. Thus, such Book has inevitably to resort to repetition. Attracting and admonishing, without repetition, would be far from eloquence. The expected effect in the souls cannot be obtained without repetition. Nevertheless, in this noble Book, the topics are so sweetly related that their repetition never bores the hearers.

Furthermore, each repetition of a subject brings fresh details and features that have not formerly been mentioned, or rather in each repetition there is an additional important gnostic or ethical point around which the case revolves.
