Quran is the Last Word of God to the mankind. The journey of Revelation lasted 23 years. It started by the word "Read" (96-1) and ended by this statement:

Today, I have perfected your religion for you and completed My favor (Quran) to you,.. (5-3)

Quran is a perfect and complete word from God to the whole mankind. Quran was revealed from God who stated that He is the Owner of Logic, Wisdom and Sciences:

027.006
Lo! As to thee (Mohammad), the Qur'an is bestowed upon thee from the presence of One who is Aware of All Wisdom (Logic) and Sciences.

The Qur’an is a sustained book for guidance of the mankind as it presents the permanent logical and scientific proof to truth the Messenger and the Religion of Islam. God says:

004.174

O people! Verily, an evident (convincing and manifest) proof has come to you from your Lord, We revealed to you a manifest light.

Quran has the logical proofs that God is reality, that He is the Creator and Sustainer of the whole Universe and of all Creations. Reading Quran, we get to Clear Facts of Oneness of Goal, we are created and we are responsible for our deeds which will be counted in the Day of Resurrection. Quran assures to God's followers that it represents true revelation from the Real God and assures the Truth of the Mohammed's message.

The Quran gave such proofs through logical questions that should be answered by an intended logical answer which involve the perfect faith in God.

As an example; we may look at the following verses from the Surah or Chapter number 52 in the Quran (Al-Tor):  It is logical questions to those who deny the existence of God.

052.035
YUSUFALI: Were they created of nothing, or were they themselves the creators?
PICKTHAL: Or were they created out of naught? Or are they the creators?
SHAKIR: Or were they created without there being anything, or are they the creators?

052.036
YUSUFALI: Or did they create the heavens and the earth? Nay, they have no firm belief.
PICKTHAL: Or did they create the heavens and the earth? Nay, but they are sure of nothing!
SHAKIR: Or did they create the heavens and the earth? Nay! they have no certainty.

052.037
YUSUFALI: Or are the Treasures of thy Lord with them, or are they the managers (of affairs)?
PICKTHAL: Or do they own the treasures of thy Lord? Or have they been given charge (thereof)?
SHAKIR: Or have they the treasures of your Lord with them? Or have they been set in absolute authority?

052.038
YUSUFALI: Or have they a ladder, by which they can (climb up to heaven and) listen (to its secrets)? Then let (such a) listener of theirs produce a manifest proof.
PICKTHAL: Or have they any stairway (unto heaven) by means of which they overhear (decrees). Then let their listener produce some warrant manifest!
SHAKIR: Or have they the means by which they listen? Then let their listener bring a clear authority.

052.039
YUSUFALI: Or has He only daughters and ye have sons?
PICKTHAL: Or hath He daughters whereas ye have sons?
SHAKIR: Or has He daughters while you have sons?

052.040
YUSUFALI: Or is it that thou dost ask for a reward, so that they are burdened with a load of debt?-
PICKTHAL: Or askest thou (Muhammad) a fee from them so that they are plunged in debt?
SHAKIR: Or do you ask them for a reward, so that they are overburdened by a debt?

052.041
YUSUFALI: Or that the Unseen Future is in their hands, and they write it down?
PICKTHAL: Or possess they the Unseen Future so that they can write (it) down?
SHAKIR: Or have they the unseen future so that they write (it) down?

Such logical questions should be answered logically. It is the logical style, from the God, who has the whole logic and knowledge, to get the logical answers through logical questions. Hence, we, as humans, get to a firm reality which is decided by ourselves. The logical answers for these logical questions may be summarized as follows:

052.035
No: It is impossible to be created in such perfect form without a Real Creator: The eyes which distinguish the seen objects by solar spectrum through complicated mechanisms, the ears which distinguish the heard speeches by turbulence or vibrations of air through highly complicated systems, the heart, Liver, kidneys, lungs, nerves, and other members which are perfectly designed and perfectly performing assigned tasks to survive. Our highly designed Skelton from the minerals of the earth in such perfect structure that sustains our power and life cannot be designed in such form without a Great Creator.

We cannot claim also that we created ourselves as we can do nothing if we loose any member of such creation.

052.036

No: It is impossible to claim that we have any favor in the creation or the management of such finely tuned and perfect universe. Such highly ordered and disciplined universe is surely created and sustained by One Creator who manages every thing in this universe in perfect mastered order. The time of one day or one complete revolution of the earth in such infinite universe is 24 hours. It never happened to be more or less. The sun radiates on every square meter of the earth 1322 kJ every second which is called the solar constant. Such constant rate of radiation from sun through humanly uncontrolled nuclear fusions cannot be designed or sustained without Great Creator. The stars which are larger from our sun are kept too far from our solar system not to attack by its light our nights. Such discipline cannot be done by any human means.

052.037

 No: We cannot claim that we have any control on the stores of clouds, rains, fresh water, carbon, magnesium, phosphorous, oxygen, nitrogen, etc. Such stores are controlled by His Design, Will and orders. The rain may not come at all or comes in floods. The clouds may visit certain locations for months and leave other locations for years. No one can control such stores. The cycles of the water, the Oxygen, the Carbon, the Nitrogen, Phosphorous, the Sulfur and every element of our thin earth's crust are designed, balanced, controlled and sustained by Him. No one can claim such stores are in his hand but God Who created, estimated, sustained and neatly controls them.

052.038

 No, as humans we have no means to climb out to listen to another world. It is impossible for the humans to cross their human nature or to be able to access to know what is above the limits of the seen universe. Our vision and knowledge are restricted to the will of God. So, no one can claim that he can go and get knowledge from any external source but the revelation that was sent to the God's messengers. Specifically, the source of the secrets of the future life and the Will of their God should be from the Quran as it is the last message to the human beings. In Quran, we can see what is after our earth's life and no way to know or listen to another source

052.039

 No. Logically God is not a human who has a family of daughters and sons. According to other verses of Quran; He is beyond our ability to see or imagine. Arabs in the time of Mohamed claimed that they worshipped daughters of God while they hated daughters for themselves. Surely, such idea is illogic as this idea means God is unable to have sons as a preferred gender. So, the logic answer is God surely had no sons or daughters but He is One, a Unique Entity that should haven't a similar son or daughter.

052.040

 No, Mohammad is a Messenger of the God who has the Whole treasures of this universe. He is not asking any reward for His Holy task. He is the God's Guide for optimum life on the earth and to the Paradise. He Had never asked any one for money but He was struggling to raise the God's word.

052.041

 No, the Unseen future is the knowledge and the authority of God. None can know or influence his future. It is the God's affairs and none can claim any authority to write or influence such future.

 Can any one claim different logical answers?
