ALLAH SWT says in Quraan in Surah Muddassir [Holy Quran – Chapter – 74, Verse – 30]:

“Over it is 19. And We have set none but angels as Guardians of the Fire; and We have fixed their number only as a trial for Unbelievers,- in order that the People of the Book may arrive at certainty, and the Believers may increase in Faith,- and that no doubts may be left for the People of the Book and the Believers, and that those in whose hearts is a disease and the Unbelievers may say, “What symbol doth Allah intend by this?” Thus doth Allah leave to stray whom He pleaseth, and guide whom He pleaseth: and none can know the forces of thy Lord, except He and this is no other than a warning to mankind.”

Like the Quran itself, the Quran’s mathematical coding ranges from the very simple, to the very complex. The Simple Facts are those observations that can be ascertained without using any tools. The complex facts require the assistance of a calculator or a computer. The following facts do not require any tools to be verified, but please remember they all refer to the original Arabic text.

Something worth pondering…..number of times the word “AL-BARR” means LAND apeears in the QURAAN = 13; while number of times the word “AL-BAHR” means   SEA  apeears in the QURAAN = 32; thus giving a total of 45 references.                                                                                                            If we divide that number by that of the number of references to the land we arrive at the figure    28.888888888889%. The number of total references to land and sea, 45, divided by the number of references to the sea in the Qur’an, 32, is 71.111111111111%. Extraordinarily, these figures represent the exact proportions of land and sea on the Earth today.
