The Holy Quran ..the book of Allah the exalted ..the absolute creator ..the supernatural knower .. who knows how mankind do , their present also their future ..so no doubt it included in-between its borders from each example..and the miracles of the Holy Quran is remaining until the day of judgment .. that is everyday more and more of its miracles are discovered ..but sorrowful we abandoned them and didn’t give them their rights ..from those many miracles The miracle of the numerical Quran which leaves no way to any wise man to doubt about it , so if it was from Mohammad’s words ( peace of Allah be upon him) from where could he had all these abilities.

And it was God willing which made the miracle of numbers as a secret until the discovery of the physicS , and that is explain the Holy verse which say :

"Soon will We show them Our signs in the (furthest) regions (of the earth) , and in their own souls , until it becomes manifest of them that this is the truth . Is it not enough that thy Lord doth witness all things )."
