God has blessed man with a guidebook in the form of the Quran. It has two special qualities. One of its qualities is that it is marked by utmost consistency. In other words, it is a book which has no contradictions. One part does not clash with another. If the Quran’s statements had not corresponded exactly with reality, there would have been differences between and inconsistencies in its various parts. The second quality of the Quran is its use of repetition, that is, its topics are often repeated in different styles. This quality in the Quran shows that it is a book of advice and guidance. An adviser always wishes that his words should establish themselves firmly in the mind of the hearer. For this purpose, he expresses the same statements in different ways. This wisdom is found in the Quran in its best form. It is the nature of man that when he hears some terrible news, or he undergoes some hair-raising experience, his inner being is humbled and his heart is softened by the news. When a serious man reads the Quran he undergoes such spiritual experiences.
