Fourteen centuries ago, Allah sent down the Qur'an to mankind as a book of guidance. He called upon people to be guided to the truth by adhering to this book. From the day of its revelation to the day of judgement, this last divine book will remain the sole guide for humanity. The matchless style of the Qur'an and the superior wisdom in it are definite evidence that it is the word of God. In addition, the Qur'an has many miraculous attributes proving that it is a revelation from God. One of these attributes is the fact that a number of scientific truths that we have only been able to uncover by the technology of the 20th century were stated in the Qur'an 1,400 years ago.
Of course the Qur'an is not a book of science. However, many scientific facts that are expressed in an extremely concise and profound manner in its aayath have only been discovered with the technology of the 20th century. These facts could not have been known at the time of the Qur'an's revelation, and this is still more proof that the Qur'an is the word of God. 
In the Quran, Allah reveals that the creation of man is a miracle. The first human being was created by Allah shaping clay into a human form and then breathing a soul into it, Allah says in Quran [So mention] when your Lord said to the angels, "Indeed, I am going to create a human being from clay. So when I have proportioned him and breathed into him of My [created] soul, then fall down to him in prostration."Quran Surah38:71-72
( إذ قال ربك للملائكة إني خالق بشرا من طينٍ ، فإذا سويته ونفخت فيه من روحي فقعوا له ساجدين ) سورة (ص) 71-72
and also says : Then inquire of them, [O Muhammad], "Are they a stronger [or more difficult] creation or those [others] We have created?" Indeed, We created men from sticky clay. Quran Surah37:11
( فاستفتهم أهم أشد خلقاً أم من خلقنا إنا خلقناهم من طين لازب) الصافات 11
When the human body is examined today, many elements present on the earth are also discovered to be found in the human body. Living tissues contain 95% carbon, hydrogen, oxygen, nitrogen, phosphorus and sulphur, with a total of 26 different elements. In another ayath of the Quran we are told: "We created man from an extract of clay" Quran Surah 23:12
(ولقد خلقنا الإنسان من سلالة من طين ) المؤمنون 12
The Arabic word "sulala," translated as "extract" in the ayath, means "representative example, essence or type of Clay." As we have seen, the information revealed in the Quran 1,400 years ago confirms what modern science tells us-the fact that the same elements as those found in the soil are employed in the human creation .
Below is a diagram showing the distribution of the elements in a 70-kilo human being.
Abû Mûsâ al-Ash`arî relates that the Prophet (peace be upon him) said: “Allah created Adam from a handful taken from all over the Earth. Therefore, the descendants of Adam came forth corresponding to the Earth. Some are red, some are white, and some are black, and some are intermediate between those. Some are easygoing, some are difficult, some are bad, and some are good.” The hadîth is related by al-Tirmidhî (2955) and Abû Dâwûd (4693). It is declared authentic by al-Albânî and others. 
All that we have seen so far shows us one clear fact: the Qur'an is such a book that all the news related in it has proved to be true. Facts about scientific subjects and the news given about the future, facts that no one could have known at the time, were announced in its verses. It is impossible for this information to have been known with the level of knowledge and technology of the day. It is clear that this provides clear evidence that the Qur'an is not the word of man. The Qur'an is the word of the Almighty God, the Originator of everything and the One Who encompasses everything with His knowledge. In one verse, God says on the Qur'an "Do they not then consider the Quran carefully? Had it been from other than Allah, they would surely have found therein much contradictions." (Qur'an Surah 4:82) Not only are there no inconsistency in the Qur'an, but every piece of information it contains reveals the miracle of this divine book more and more each day.
What falls to man is to hold fast to this divine book revealed by God, and receive it as his one and only guide. In one of the verses, God calls out to us:
"And this is a Book We have sent down and blessed, so follow it and have fear of God so that hopefully you will gain mercy." (Qur'an Surah 6:155)
In His other aayaath, Allah remarks: "Say: 'It is the truth from your Lord. Let anyone who wishes to, believe, and let anyone who wishes to, disbelieve.'" (Qur'an Surah 18:29)
