In 46:30 we read that the Qur'an " guides to the truth and a right road, ” meaning the road of right belief and correct action. On another occasion, mentioning the Torah and the New Testament, God says, " We have revealed this Book to you with the Truth, confirming whatever Book was before it, and We keep watch over it " (5:48). The Qur'an thus affirms the truth of the ways of guidance taught by the earlier prophets.
In chapter 42:13, " He has ordained for you that religion which He commended to Noah and that which We reveal to you (Muhammad) and that We commended to Abraham, Moses and Jesus, " and in chapter 16:89, " And We revealed the book to you as an exposition of all things. " Thus we understand from these verses that the Qur'an not only encompasses the meanings and teachings of all divine books revealed before it, but also adds to and completes them.
Everything which a man needs, both in terms of his spiritual and his social life, is contained and explained in the Qur'an. The Eternal Quality of the Qur'an The perfection and completeness of the Qur'an prove that its validity is not restricted to a particular time or place, since anything perfect is in need of nothing to complete it.
In chapter 86:13-14 God confirms that the Qur'an is " a conclusive word " and not a mere " pleasantry ." It contains the purest of teachings concerning belief in life-after-death, together with an exposition of the realities of existence, while, at the same time, encompassing the fundamentals of correct human behavior. Since laws governing transactions between men are directly linked to their beliefs, such a book can obviously not be annulled or changed with the passage of time.
As He says in 17:105, " We have revealed the Qur'an with Truth and it has descended with the Truth, " meaning that the revelations and their ongoing validity are inseparable from the Truth. Thus in 10:32, " After the Truth what is there except error,” and in 41:41-42, " In truth it is an impenetrable book, error may not enter in it from before it or behind it.
" In other words the Qur'an repulses, by its own perfection and completeness, any attempt to alter it; and neither now nor later can it be annulled or superseded. Many studies have been made of the permanence of the validity of the laws given in the Qur'an.
