Are there any well known quotes from the Koran which explain how you can know Allah through FAITH?

Allah SWT has revealed himself to us through the Holy Quran. Thw whole Quran is Allah word. Allah says if you doubt it then produce a verse like it.

"Say: If the whole of Mankind and Jinns were together to produce the like of this Qur’an they could not produce the like thereof, even if they backed up each other with help and support." [Al-Qur’an 17:88] 

"And if you are in doubt as to what We have revealed from time to time to Our servant, then produce a Surah like thereunto; and call your witnesses or helpers (if there are any) besides Allah if your (doubts) are true. But if ye cannot – and of a surety ye cannot – then fear the Fire whose fuel is Men and Stones – which is prepared for those who reject faith". [Al-Qur’an 2:23-24] 

Quran :-

>The grammar of the Quran is perfect without one mistake. If you know Arabic grammar, then you will know that it is 100 times more in depth and complicated than English

>Statistical miracles in the Quran http://www.islamawareness.net/Miq/stat.html

>Scientific miracles in the Quran http://www.onereason.org/islam-unveiled/why-islam/

>Then add that there is no contradiction between one statement and another from 114 chapters

>The rhyming melody of the qur'an is so perfect - that it can't be duplicated. It does not conform to any poetical order of Arabic or any other language.

You can't call it poem nor prose. Quran is just Quran. Its lucid, lyrical and mellifluous style is not less than any miracle.

>Not ONE syllable is out of place in the perfect mathematical rhyming scheme

>No one have changed or altered the book - Then every statement is a statement of truth, along with that every single sentence is timeless, meaning it is true now and will always be true

Concept of God in Islam - http://quran.com/112

Suppose someone discovers a paper in the desert which contains all the letters of the alphabet in order from a to z. Then the conscience of every man will bear witness that the writing of those letters and their sequence is the result of understanding and perception. If he finds on the paper a word composed from those letters or a symmetrical speech, then he will believe that the composer is knowledgeable and well-informed. He will reason that the composer has knowledge and wisdom.

Then, is the formation of a plant from its basic origin, a lesser indicator of the knowledge and wisdom of its Creator than the composition of a sentence, which is an obvious indicator of the knowledge of the composer? What is wrong with man that with one sentence, he reasons that its composer has knowledge and wisdom? Yet, with a plant, he fails to reason that its Creator has knowledge and wisdom.

What is this wisdom and knowledge that made a plant from water and soil that decays the husk of the seed, and gives life to its core?

He gave the root of a plant the power to tear out from the earth and draw nourishment from the darkness of the soil. From every piece of land, He has prepared nourishment for different kinds of plants and trees. Every plant and tree finds its nourishment from the soil. He has made the roots of all trees draw only the nourishment specific to them, resulting in their specific fruits.

He made the roots combat the gravity of the earth, thus, they send water and nourishment to the branches and the twigs of the tree. While the roots work in the depths, He made the branches, twigs and leaves work to attain light and air. Therefore, He made everything easy when He created it.7

No matter how hard the human being works in changing this wise practice, to make the roots go up to the sky—which are made to go to the depths of the ground, and to make the branches go in the ground—which are made to work in air, they will find them combating this human practice. They continue their natural course:

and you shall not find any change in the course of Allah.8

Pay attention to the creation of a tree, from the stem to the thousands of leaves; indeed, it is a marvellous structure that amazes the intellects. What gave each one of the cells of the leaves the power to absorb water and nourishment from the depths of the earth through the roots? Who gave them the connection between the sky and earth? The difference between day and night, and the harmony in growth, which finishes the seed in its roots and branches but preserve it in its fruits, why is this law of nature effective in its life? It is sufficient for mankind to believe in the endless knowledge and wisdom behind it.

Nay, He Who created the heavens and the earth, and sent down for you water from the cloud; then We cause to grow thereby beautiful gardens; it is not possible for you that you should make the trees thereof to grow. Is there a god with Allah? Nay! They are people who deviate.9

Is it you that produce the trees for it, or are We the producers?10

We cause to grow in it of every suitable thing.11

Indeed, whichever plant or tree you look at, you will find from its roots to its fruits, a sign of the Creator’s knowledge, power and wisdom. They surrendered in their way, which has been made for their nurture and guidance:

And the herbs and the trees do prostrate (to Him).12
