O people, worship only your Lord - the One who created you and
                 those before you - that you may be saved.
              The One who made the earth habitable for you, and the sky a structure.
He sends down from the sky water, to produce all kinds of fruits for your sustenance.
You shall not set up idols to rival GOD, now that you know.
              If you have any doubt regarding what we revealed to our servant,
then produce one sura like these, and call upon your own witnesses against GOD, if you are truthful.
              If you cannot do this - and you can never do this - then beware of
                 the Hellfire, whose fuel is people and rocks; it awaits the disbelievers.
[al-Baqarah 2:21-24]

Say, "Who provides for you from the heaven and the earth?
Who controls all the hearing and the eyesight?
Who produces the living from the dead, and the dead from the living?
Who is in control of all things?"
They would say,
 "GOD."
Say, "Why then do you not observe the commandments?"
Such is GOD, your rightful Lord. What is there after the truth, exceptfalsehood?
How could you disregard all this?
   This is what your Lord's decision does to those who choose to be
wicked: they cannot believe.
         Say, "Can any of your idols initiate creation, then repeat it?"
Say,
"GOD initiates the creation, then repeats it."
 Say, "Does any of your idols guide to the truth?
" Say, "
GOD guides  to the truth. Is one who guides to the truth more worthy of being followed,
or one who does not guide, and needs guidance for himself?
What is wrong with your judgment?"
 Most of them follow nothing but conjecture, and conjecture is no
                 substitute for the truth.
GOD is fully aware of everything they do.
 This Quran could not possibly be authored by other than GOD.
It confirms all previous messages, and provides a fully detailed scripture.
It is infallible, for it comes from the Lord of the universe.
If they say, "  He fabricated it,
" say, "
Then produce one sura like these, and invite whomever you wish, other than GOD, if you are truthful."
Indeed, they have rejected this without studying and examining it,
                 and before understanding it.
Thus did those before them disbelieve.
Therefore, note  the consequences for the transgressors.
[Yunus 10:31-39]

 As for those who steadfastly persevere, and lead a righteous life, they
                 deserve forgiveness and a generous recompense.
              You may wish to disregard some of that which is revealed to you, and
                 you may be annoyed by it.
Also, they may say, "How come no treasure comes down
                 to him, or an angel?"
You are only a warner; GOD controls all things.
           If they say, "  He fabricated   (the Quran)," tell them,
"Then produce ten   suras like these, fabricated, and invite whomever you can, other than GOD,
if you  are truthful."
           If they fail to meet your challenge, then know that this is revealed with GOD's knowledge, and that there is no god except He.

          Those who pursue this worldly life and its material vanities, we will pay
                 them for their works in this life, without the least reduction.
[Hud 11:11-15]

What Is A
"Gematrical Value"?

 When the Quran was revealed, 14 centuries ago, the numbers known today did not exist. A universal
 system was used where the letters of the Arabic, Hebrew, Aramaic, and Greek alphabets were used
 as numerals. The number assigned to each letter is its "Gematrical Value." The numerical values of
                       the Arabic alphabet are shown in this table
