"3β We have made it a Qur’an in Arabic, that you may be able to understand. 4 β And verily, it is in the Mother of the Book, in Our Presence, high (in dignity), full of wisdom." XLIII:3 & 4
"Allah doth obliterate (blot out) or confirm what He pleaseth. With Him is the Mother of the Book." XIII:39
The term "Mother of the Book" (or the Mother Book) is believed to represent the Full Knowledge, the essence of all Divine revelations without regard to time and space, the codes known to Him but not understandable by us. It does not necessarily represent a physical book. The following ayat may explain better. It should be clear that this subject is a very large one on which volumes of deep discussions have been rendered, with various points of view. Therefore, no claim is made in this brief writing that this interpretation is the only one or the true one:
"Say to whoever is an enemy to Jibril: for certain he brings down the (revelation) to thy heart by Allah's will, a confirmation of what went before, and a (book of) guidance and glad tidings for the believers. " II:97
"It is not but wahy that is revealed." LIII:4
"Thus doth (Allah) send wahy to thee as (He did) to those before thee, Allah exalted in Power, full of Wsdom." XLII:3
"Say: I am but a man like yourselves, (but) the wahy has come to me, that your Allah is one Allah ...." XVIII:110
"51 β It is not fitting for a man that Allah should speak to him except by wahy, or from behind a veil, or by the sending of a rasul to reveal, with Allah's permission, what Allah wills. For He is most High, Most Wise. 52 β And thus have We, by Our command, sent inspiration to thee. Thou knowest not what was Revelation, and what was Faith. But We have made (the Qur’an) a Light, wherewith We guide such of Our obedient as We will. And verily thou dost guide to the Straight Path." XLII:51β52
Almighty Allah tells us explicitly that there are three ways in which He bestows His revelation on mankind:
A. Wahy: Inspirations may occur in many forms, ranging from a simple and common dream and telepathy, to much more elevated forms of vision and the Divine revelation. In the English language, the word "revelation" is used for all who reveal, being the journalists, politicians, writers, or God! Therefore, the Arabic term wahy is used here for that which is uniquely a Divine revelation. Another point to clarify is that the subjects of inspiration are human beings, in general, whereas the subjects of wahy are chosen Messengers of Allah, the Exalted. In lower forms of wahy, signals are stimulated by Allah the Exalted into the heart and mind of a Messenger who understands the substance of the Message, whether it is a command or prohibition, or an explanation of a great truth. It is quite logical that the more elevated a Messenger, the greater is the value of the message, the quality of its reception and the impact of such a message. In its perfect form, verbal or literal wahy is transmitted in such a way that the actual words of Almighty Allah are conveyed in human language, uttered by the human tongue. This superior β recited β form of wahy is only granted to the greater Prophets, while lower forms may be bestowed upon other Prophets. It is important to realise that not all inspirations or revelations are heavenly. Satan, angels, and humankind may inspire people and reveal certain affairs. This is how many people are deceived by specific ominous visions and inspirations. The safest revelation is that in which Allah the Exalted sends an Angel to recite the wahy personally to His Chosen Messenger, as will be covered under C) below.
B. Behind a veil: Not, of course, a material veil, or screen, but a mystic Veil of Light. There are quotations from Muhammad (SA), saying: "Allah has some seventy thousand Veils of Light and Darkness. Were He to with draw their curtain, then would splendours of His Aspect (or Countenance, or Face) surely consume everyone who apprehended Him with his sight: ' This is a very large subject which has been studied by numerous scholars. This subject will be only briefly introduced in this book (see the mystic elements of the Glorious Qur'an, page 38). For more information, one could start with Appendix VIII of the Glorious Qur'an translated into English by A. Yusuf ‘Ali.
C. Rasul (apostle of Allah): The revelations are delivered to the Holy Messenger of Allah through the Angel Gabriel (PBUH), as mentioned earlier, in the purest and most confident form. These spiritual visions, conveying the message of Revelation, are the basis of the Noble Quran.
Another important point in the above ayah is: "We have made (the Quran) a Light, wherewith We guide such of Our obedients as We will." There is another ayah to complement the above:
"O mankind! Verily there had come to you a convincing proof from your Lord. For We have sent unto you a Light (that is) manifest (muban)." IV:174
The Light refers to the Glorious Qur'an and its manifestation is the character and personality of Muhammad (SA) himself. He is known to be the walking Qur'an. Extensive volumes of traditions (ahadith) fail to give evidence to one single incidence indicating that he (and his kinfolk) deviated from βthe Qur'anic way. Therefore, his life should be taken as a perfect model to follow for those who wish to be guided according to the Holy Qur'an.
