Now observe how the Quran has been named “The Reminder” (Al-Dhikr), because it reminds mankind of the law present within. When a subject-noun is converted to the infinitive form, this also brings it to the measure of the superlative degree. Let us presume that someone said:
What would this mean? This means that Zayd is exceedingly just. The Quran has not brought a new law, but rather reminds man of the inner law present within man in the form of various faculties. There is forbearance, kindness, bravery, might, anger, contentment, etc. Hence, the Quran has reminded us of the nature vested within us. Just as Allah the Exalted states:
فِی کِتَابٍ مَّکْنُوْنٍ
In other words, this is the hidden scripture present in the Book of Nature, which all people did not have the ability to see. As such, this book was named “The Reminder” so that when it is recited, it reminds us of the inner, spiritual faculties, and the light of the heart vested in man from heaven.
Hence, Allah the Exalted has manifested a spiritual miracle by sending down the Quran, so that man may discover the insights, verities and spiritual wonders of which he was previously unaware. The ultimate cause of the Quran is:
“A guidance for the righteous.” It is unfortunate, however, that this has been forgotten and the Holy Quran is considered to be nothing more than a collection of a few stories. Like the idolaters of Arabia, they indifferently and insolently declare the Quran to be tales of the past and turn a blind eye to this book. The previous age was the era in which the Holy Prophet, peace and blessings of Allah be upon him, appeared and in which the Quran was revealed, reminding people of that age of their inner strengths.
Now that era has arrived about which the Holy Prophet, peace and blessings of Allah be upon him, had prophesied that the people would recite the Quran, but it would not go beyond their throats. You can now see with your own eyes how people melodiously and beautifully recite the Holy Quran, but the Quran does not go deeper than their throats.
Therefore, the Holy Quran, which is also named “The Reminder”, came in this early period to remind people of the hidden and forgotten truths and innate qualities within man.
