look at it more closely:
رب ب ك ف ك ب ب ر
Rabbaka-fa-Kabbir…when you look at it both ways! SubhanAllah! In English, this is called a “palindrome”, when a word is looked at backwards and forwards and has the same spelling. (race car, radar, mom etc).
In order to construct a palindrome, one would have to look up words, check their spellings, find their definitions, write it down a few times to see if it works and so on…a lot of work! BUT:
1- The Prophet sal Allahu alayhi wa sallam was an Nabiyy al Ummiyy: he couldn’t read.
2- The Qur’an was not revealed as a written book; but it was oral.
3- The Qur’an was not edited, it was not revised, it was one attempt.
4- Furthermore, the Prophet sal Allahu alayhi wa sallam didn’t even mention this literally miracle in his lifetime! He did not say: ‘look this ayah is a palindrome, become Muslim!’ This was discovered by the scholars of tafseer, who were so meticulous and intricate with the Qur’an that they counted how many letters, how many times this word comes, how many times that letter comes and more–The study of statistics in the Qur’an started in the second or third century.
The Qur’an is a challenge for humanity; it doesn’t compromise style and content so if someone intended to duplicate this book, they would have to have both. Race car has the style (of a palindrome), but it does not have the same content as Rabbaka faKabir.
Even if the humans and jinn were to get together, they chose any language, would they be able to create “Rabbaka faKabir” as a palindrome that contains both content and style?
And the irony is in the meaning of the ayah itself: declare the greatness only of your Rabb.
Allahu Akbar.
