Allah has sent down miracles, revelations and messengers to give clear proofs He exists and more important, what we should do once we come to this realization.
Allah has sent prophets and messengers with many proofs throughout the ages for people to be able to clearly see with their own eyes and to be able to use their own senses the miracles and proofs pointing to the fact, Allah does in fact, exist.
Miracles of prophets and messengers of Allah have come to people through the ages. Moses (peace be upon him) showed many miracles to pharaoh and to the children of Israel. Plagues, locusts, water turning to blood, his stick becoming a snake, the voice in the burning bush and the parting of the Red Sea are clear miracles for the people of Moses time.
Again, Allah sent Jesus, the son of Mary (peace be upon him) with clear miracles for the people of his time. Speaking from the cradle while still a new born infant, creating birds from clay, curing the sick, giving sight to the blind and even bringing a dead man back to life, were all clear signs to the people to know Jesus (peace be upon him) was a messenger of Allah as was Moses before him.
Muhammad (peace be upon him) was the last and final messenger of Allah, and he was sent to all of mankind. Allah sent him with a number of miracles, not the least of which was the Quran. The predictions and prophecies of Muhammad (peace be upon him) have come true even in this century and the Quran has been used to convince even scientists of the existence of Allah.
The Quran is the best of proofs for the existence of Allah and today over one and half billion people memorize and recite from the exact text, in the exact same language it was revealed in; Arabic. More than 10 million Muslims have completely memorized the entire Quran from cover to cover, and can recite it from memory without looking at it.
No one sees or hears Allah, not even the prophet Muhammad (peace be upon him). Nor are we able to use our senses to make some kind of contact with Him. However, we are encouraged in Islam to use our senses and our common sense to recognize this entire universe could not possibly come into existence on its own. Something had to design it all and then put it into motion. This is beyond our ability to do, yet it is something we can understand.
We know from the teachings of Muhammad (peace be upon him) the proofs for the existence of God (Allah) are most obvious to us in our everyday surroundings. Anyone with understanding would quickly acknowledge His existence provided they are not so stubborn as to ignore the obvious evidences right in front of us.
We don’t have to see an artist to recognize a painting, correct? So, if we see paintings without seeing artists painting them, in the same way, we can believe Allah created everything without having to see Him (or touch, or hear, etc

The Qur’an is a clear miracle which need not be introduced. It invites others to itself, demands the rejecters to challenge it while it defeats them, condemns them, and it always stands victorious. That is why it, after passing centuries, viz., since the departure of the Prophet (p.b.u.h.) up to the present, has been continuing its invitation the same as it did during his lifetime (p.b.u.h). It is both religion and miracle; law, and the document of the law.
The Holy Qur’an, Global and Eternal
The reputation of the Holy Qur’an cleft the bonds of time and distance and influenced beyond them. The miracles of the prophets before the Prophet of Islam (p.b.u.h.), and even his own miracles save the Qur’an, happened in a special period of time, at a definite place and for a specific group of people. For example : the utterances of the holy little child of Virgin Mary, and raising the dead by Jesus (a.s.) were done at some definite times and places before the eyes of some particular people. And we know that regarding the things that depend on time and place, the farther we move away from them correlatively the weaker they become. This is one of the properties of affairs related to time.
But, the Holy Qur’an does not depend on time and place. Its brilliance and authority that illuminated the darkness of Arabia fourteen centuries ago continues unwaveringly to shine with its original splendor. Besides that, the passing of time, the advancement of science and the development of information have made it possible for us to understand it and take its advantages even more than the nations of former ages did. It is evident that what time and place cannot influence will continue to be everywhere in the world for eternity. It is also clear that a world-wide everlasting religion should have a world-wide everlasting document of legitimacy in its possession.
Not only with science. It is a book of history, philosophy, laws and many more. An unique book to guide the humanity.
Then we can discuss the Holy Qur’an :
from the point of modern science;
and the scientific explorations;
and the rotation of the Earth;
and reproduction in the plant kingdom;
and general reproduction in all the particles of the world;
and general gravity;
and the surrendering of the Sun and the Moon;
and the secrets of the creation of mountains;
and the advent of the world;
and the existence of life on other planets;
and the winds, the pollinator of plants;
and the question of the roundness of the Earth; (2)
And many other scientific facts and knowledge about the world can be found in the Holy Qur’an, too.
