Examples of the Miracle of the Qur'an
Whoever reads through the Qur'an will realize that it contains various levels of superiority through both the apparent and hidden meanings that it mentions. Allah said,
[الركِتَـبَأُحْكِمَتْ ءايَـتُهُ ثُمَّ فُصِّلَتْ مِن لَّدُنْ حَكِيمٍ خَبِيرٍ]
(Alif Lam Ra. (This is) a Book, the verses whereof are perfect (in every sphere of knowledge, etc.), and then explained in detail from One (Allah), Who is Wise and well-acquainted (with all things)) (11:1)
So the expressions in the Qur'an are perfect and its meanings are explained. Further, every word and meaning in the Qur'an is eloquent and cannot be surpassed. The Qur'an also mentioned the stories of the people of the past; and these accounts and stories occurred exactly as the Qur'an stated. Also, the Qur'an commanded every type of righteousness and forbade every type of evil, just as Allah stated,
[وَتَمَّتْ كَلِمَةُ رَبِّكَ صِدْقاً وَعَدْلاً]
(And the Word of your Lord has been fulfilled in truth and in justice) (6:115). meaning, true in the stories it narrates and just in its Laws. The Qur'an is true, just and full of guidance. It does not contain exaggerations, lies or falsehood, unlike Arabic and other types of poems that contained lies. These poems, conform with the popular statement, "The most eloquent speech is the one that contains the most lies!'' Sometimes, one would find a long poem that mainly contains descriptions of women, horses or alcohol. Or, the poem might contain praise or the description of a certain person, horse, camel, war, incident, fear, lion, or other types of items and objects. Such praise or descriptions do not bring any benefit, except shed light on the poet's ability to clearly and eloquently describe such items. Yet, one will only be able to find one or two sentences in many long poems that elaborate on the main theme of the poem, while the rest of the poem contains insignificant descriptions and repetitions.
As for the Qur'an, it is entirely eloquent in the most perfect manner, as those who have knowledge in such matters and understand Arabic methods of speech and expressions concur. When one reads through the stories in the Qur'an, he will find them fruitful, whether they were in extended or short forms, repeated or not. The more these stories are repeated, the more fruitful and beautiful they become. The Qur'an does not become old when one repeats reciting it, nor do the scholars ever get bored with it. When the Qur'an mentions the subject of warning and promises, it presents truths that would make solid, firm mountains shake, so what about the comprehending, understanding hearts When the Qur'an promises, it opens the hearts and the ears, making them eager to attain the abode of peace - Paradise - and to be the neighbors of the Throne of the Most Beneficent...
