Some aspects of the inimitability of the Qur`an

The Noble Qur`an is inimitable in its words and rhetoric: And if you (Arab pagans, Jews, and Christians) are in doubt concerning that which We have sent down (i.e. the Qur`ân) to Our slave (Muhammad صلى الله عليه وسلم), then produce a Sûrah (chapter) of the like thereof and call your witnesses (supporters and helpers) besides Allâh, if you are truthful.

It is inimitable in the easiness of its understanding and recitation: And We have indeed facilitated the understanding and remembering of the Qur`ân; then is there any one who will remember (or receive admonition)?

It is inimitable in the narratives of past nations it relates to derive lessons: We relate unto you (Muhammad صلى الله عليه و سلم) the best of stories through Our Revelations unto you, of this Qur`ân. And before this (i.e. before the coming of Divine Revelation to you), you were among those who knew nothing about it (the Qur`ân). Allaah (Free from any imperfection) also says:
Indeed in their stories, there is a lesson for men of understanding. It (the Qur`ân) is not a forged statement but a confirmation of (Allâh’s existing Books) which were before it [i.e. the Taurât (Torah), the Injeel (Gospel) and other Scriptures of Allâh] and a detailed explanation of everything and a guide and a Mercy for the people who believe.

It is inimitable in the beliefs and laws it contains that entail submission: Alif-Lâm-Râ. (This is) a Book which We have revealed unto you (O Muhammad صلى الله عليه و سلم) in order that you might lead mankind out of darkness (of disbelief and polytheism) into light (of belief in the Oneness of Allâh and Islâmic Monotheism) by their Lord’s Leave to the Path of the All-Mighty, the Owner of all Praise. And We have sent down to you the Book (the Qur’an) as an exposition of everything, a guidance, a mercy, and glad tidings for those who have submitted themselves (to Allâh as Muslims). Verily We have sent down the Book to you (O Muhammad صلى الله عليه وسلم) in truth: So worship Allâh (Alone) by doing religious deeds sincerely for Allâh’s sake only. And this is a blessed Book (the Qur`ân) which We have sent down, so follow it and fear Allâh (i.e. do not disobey His Orders), that you may receive mercy (i.e. be saved from the torment of Hell).

It is inimitable in the news about Ghayb (the Unseen) it contains that inspires faith and submission: http://alifta.org/_layouts/images/UserControl-Images/MEDIA-B1.GIFAlif-Lâm-Mîm. This is the Book (the Qur`ân), whereof there is no doubt, a guidance to those who are Al-Muttaqûn [the pious believers of Islamic Monotheism who fear Allâh much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allâh much (perform all kinds of good deeds which He has ordained)].
 It is the evident sign and superb proof of the prophethood of the Messenger (peace be upon him) until Allaah commands it be taken up to heaven. Allaah (The Most High) challenged with it the most eloquent, but they failed. The challenge was even extended to all Jinn and mankind assembled together, but they could not face it: Say: "If the mankind and the jinn were together to produce the like of this Qur`ân, they could not produce the like thereof, even if they helped one another." Allaah (The Most High) conferred it upon His Prophet (peace be upon him): And indeed, We have bestowed upon you seven of Al-Mathâni (seven repeatedly recited Verses), (i.e. Sûrat Al-Fâtihah) and the Grand Qur`ân. It guides to the right path and the straight methodology:  Verily, this Qur`ân guides to that which is most just and right.
