In the following verse of the Qur'an, "… This is a Book We have sent down to you so that you can bring mankind from the darkness to the light, by the permission of their Lord, to the Path of the Almighty, the Praiseworthy." (Surah Ibrahim: 1), Allah explains that one of the blessings conferred through the sending down of the Qur'an is that it "brings people from the darkness to the light."

The Qur'an has been under Allah's protection from the time it was first revealed to the present, and has undergone no corruption. It was sent down as an admonition and a warning to people; for the faithful, it is the source of healing, guidance and a mercy. Its words are the most noble, they distinguish right from wrong, and guide those who follow it to the true path.

Those who understand the divine wisdom of the Qur'an take it as their guide. Since they have accepted the verses of the Qur'an with their entire hearts, the morality expounded in it is always reflected in their speech. At every stage of their lives, whether formulating a decision, or speaking, or while offering an interpretation of something, they consistently use the Qur'an as their guide. Therefore, their every word, every decision, and every form of advice they are prepared to offer is in agreement with the Qur'an. Those who speak by using the Qur'an as their guide invariably participate in any conversation in the best way, because the verses of the Qur'an deconstruct and eradicate all errant forms of logic, bringing the truth to the light. Allah explains this with the following verse: "Rather We hurl the truth against falsehood and it cuts right through it and it vanishes clean away!…" (Surat al-Anbiya': 18)

Words spoken in accordance with the morality explained in the Qur'an are a healing and a mercy for the sincere. Those who listen to them, with the intention of profiting from its advice, or to derive its benefits or to discern its wisdom, find the truth, by way of these conversations–if Allah wills.

In addition, the speech of those who speak in conformity with the guidance of the Qur'an has achieved wisdom. Every example they employ, every point to which they draw attention, and every detail they stress, is effective and thought-provoking. They encourage the people they address to think honestly and sincerely, and to exercise their conscience. Since their speech is sincere, issuing from their hearts, and is in defense of the right, its power to influence is strong. Those who are able to evaluate what they hear according to their conscience can verify the truth of their statements with certainty.

Those who listen, but who are insincere, and do so with prejudice, do not wish to see the wisdom and truth of the words of the faithful, but try instead to distort them through calumny. Unable to grasp that it is the wisdom of verses of the Qur'an that has reinforced the believers' speech, they attempt to explain it away through ridiculous assumptions. The fact is, however, these effects are faith-induced, and easily accessible to all who conform to the Qur'an and accept it as his guide. However, this the unbelievers fail to understand.

A number of examples of what we are discussing have been provided in the Qur'an. For example, when confronted with the frankness and wisdom direct of the Prophet Muhammad (saas), the disbelievers and pagans were plunged into dismay. Within only a short time, large numbers were moved by the message of our Prophet (saas), and their obedience to him caused great consternation among the disbelievers. Because they could not understand the verses of the Qur'an, which imbued the statements of our Prophet (saas) with their wisdom and effectiveness, or rather, that they refused to accept it, they sought to foment false accusations against him, such as that he was a magician or merely a poet. In fact, as is the case with all human beings, it is Allah Who instilled in the Prophets the power of their speech. In the verses of the Qur'an Allah declared:

Your companion is not misguided or misled; nor does he speak from whim. It is nothing but Revelation revealed. (Surat an-Najm: 2-4)

As we can see in these verses, the words of our Prophet (saas) were not only extremely effective but imbued with wisdom, because he recited from the Qur'an, a book which is the word of Allah. The One Who imparted the faith and influence to the hearts of those who listened to his words and believe, was Allah. Those who fail to appreciate the greatness of Allah fall into a grave error, by vainly seeking to gain influence and wisdom by other means.
