The Qur'an is the last scripture that has been revealed to mankind by the Lord Creator and Protector. It was through the last messenger, Muhammad (pbuh), that the world first heard of it. It certainly the Divine scripture that is to be accepted by all, up to the very last man. The term 'Qur'an' has the meanings of 'the recitation', or 'that which is to be recited' and of 'that which is recited.' Indeed, the Qur'an itself has employed the connotation 'the scripture that is recited' in connection with this term (13:31). Unlike the earlier scriptures, the Qur'an is never a compilation of legal pronouncements or code of laws (Taurat), or hymns (Zaboor) or a collection of Gospel of good news (Injeel). It is highly probable that the Qur'an has been named as the last scripture because each one of its words is to be repeatedly read by thousands upon thousands of its believers and is to be so etched into their hearts as to mould their very lives according to its guidelines. As for the actual reason, it is the Lord Who sent it Who knows the answer thereof.
As far as its believers are concerned, the Qur'an is but the criterion to distinguish truth from falsehood. They understand that all that has been commanded therein constitute the good and all that has been prohibited therein constitute evil. In fact, the Qur'an introduces itself as Furqaan (2:53, 2:185, 3:4, 25:1) which means 'the criterion to distinguish between truth and falsehood.' The Qur'an also describes itself as Kitab (book), Dhikr (guidance), Burhaan (evidence), Shifa (cure), Kayyim (that which is pure), Muhaymin (that which preserves the previous scriptures) and the like. Through these attributes the reader of the Qur'an is exposed to the clear picture of the morality enshrined within.
