That is where you consistently go wrong. It is not at all obviously true, the Quran is simply one of many texts that claim internally to be true. Moreover, you cannot legitimately cite the Quran in support of its own authority, that's not a logically valid argument, it's a tautology and begs the question. You're claiming in effect that the book is correct because it claims to be correct. That's no different from me claiming that everything I've ever posted is obviously true because everything I've ever posted is obviously true. How long will it take before you suggest we should destroy all books but the Quran, with the possible exception of certain commentaries on it? That certainly seems to be the direction you're going: if they're consistent with the Quran, they're superfluous, and if they're not, they're heretical. But actually, if that commentary of Al-Hilly's you keep referring us to is any indication, a book that's consistent with the Quran can be almost entirely wrong.
It will be sufficient to tell any man - for one time only - concerning the Glorious Quran, and then the evidence will be against him if he does not believe; that is because he has been warned by the Quran of God. Then he cannot later on deny this fact, that he became aware of the word of God.
Therefore, I am not trying to convince you, but merely to tell the readers who read your fallacies which you give the appearance of the truth, by the way of your good English expression.
The evidence is speaking about itself; if I read your words, I shall know a lot about you; and if you read my words, you too will know a lot about me. Therefore, when one reads the parables of Jesus and their deep implication he will discover that this man was sent by God; and if man reads the Quran, he will know that this is the word of God, to which many people have responded and converted.
Example: to this aya 24: 40 and its translated meaning in English, a doctor in the British Navy reacted and converted many years ago, while thousands and millions had read the same aya and may be the translation of its meaning in different languages, but were not influenced in the same way.
This is in the Quran 24: 40
أَوْ كَظُلُمَاتٍ فِي بَحْرٍ لُّجِّيٍّ يَغْشَاهُ مَوْجٌ مِّن فَوْقِهِ مَوْجٌ مِّن فَوْقِهِ سَحَابٌ ظُلُمَاتٌ بَعْضُهَا فَوْقَ بَعْضٍ إِذَا أَخْرَجَ يَدَهُ لَمْ يَكَدْ يَرَاهَا وَمَن لَّمْ يَجْعَلِ اللَّهُ لَهُ نُورًا فَمَا لَهُ مِن نُّورٍ
The explanation:
(Or [the parable for the idolater and associater and his work in this World is]
as depths of darkness on a deep sea covered by billows [of water], above which are billows [of air], above which are clouds; [and the time was at night; so it was overwhelming darkness:]
layers of darkness piled one upon another [: the darkness of the night, the darkness of the cloud and the darkness of the sea];
when he puts forth his hand, he almost cannot see it [because of the extreme darkness].
[This associater and idolater was embarking on a ship which is sailing on the sea; then his luggage or food fell in the sea; will he find it?
No, he will not find anything of it: because if it is heavy, it will go to the bottom of the sea;
while if the luggage and food is light, the waves of the sea will take it away, and he will loose his luggage and food {that he prepared for the voyage};
so similarly the work and deeds of the associater will go away and he will not be rewarded for any of his work and deeds, and he will not find any of that in the next life of the Hereafter.]
And to whomsoever God assigns no light [: a guide to guide him], no light has he [i.e. he will have no guide to guide him to the way of the truth]
[Therefore, man has to ask God to guide him, and say:
"My Lord, if I am on a correct way, then affirm me on it;
but if I am in error, then guide my heart to the way of the truth, and made clear, for me the reason for Your guidance, and let me succeed in deserving Your good pleasure; You are All-Able to do whatever You please."]
[Then, God will answer his prayer, but on condition that this man is kind-hearted, is merciful to the poor and needy, is not a wrong-doer, neither is he a hypocrite nor a miser or niggard; because God dislikes the hypocrites, the wrong-doers and the miser, and He does not guide them] )

This doctor saw many tempests and storms in the sea; so he asked: had Mohammed gone in any voyage by the sea? They told him: he never went in any voyage on sea; he merely went in two journeys by land to Syria. So he said: Such description can only come from one who knows the sea very well; therefore this Quran was not invented by Mohammed; it is obviously from God Almighty.
But the disbeliever may not admit and believe unless he is guided or else he will not.
