The contents of this book were originally presented in the form of videotape, in which several meetings and dialogues were conducted with well-known scientists in different fields of science. This was done to examine the scientific facts mentioned in several Qur'anic verses, and to highlight the fact that the religion ofIslam encourages science and the acquisition of knowledge with absolutely no contradiction between the Qur'anic revelation and the scientific facts. The scientists who participated in these dialogues were all non- Muslims, most of whom were explaining some scientific facts which they have realized only very recently and after several years of research and study. When they were told that what they have just discovered recently was already referred to either directly or indirectly in the Holy Qur'an more than 1400 years ago, they showed a great deal of astonishment. Their comments were varied, but almost all of them confessed that this Qur'an could not have come from any human or ordinary source. Indeed, some of them were convinced and have affirmed that the Prophet Muhammad (peace be upon him) is a messenger from Allah, to the point that one of them even embraced Islam by declaring the Islamic creed otherwise known as the "Shahaadah" and thus became a Muslim. When those experts and authorities ofscience acclaim these facts, they actually demonstrate a proof of the truthfulness of Islam in front of their fellow scholars and to those endowed with less knowledge among their own people. They are actually opening closed doors and paving the road to the true faith in Allah, the Lord of the universe. What then, is the excuse of those who tum away from faith after these proofs and the testimonies of those scientists? Allah also said to them in the Qur'an: Say: Do you see? If this teaching is from Allah, and you reject it, and a witness from among the children of Israel testifies to its similarity (with earlier scripture), and has believed? While you are arrogant (How unjust you are!). Truly, Allah guides not a people unjust. (Qur'an 46:10) Allah also said in the Qur'an: Those whom Allah wills to guide, He opens their breast to Islam; Those whom He wills to leave straying, - he makes their breast close and constricted, as if they had to climb up to the skies: thus does Allah lay abomination on those who refuse to believe. (Qur'an 6:125). The original dialogues with those scientists were recorded on a videotape entitled "This Is The Truth". They are far more effective and a lot clearer to a viewer. To make this exchange ofideas available to a wide range of people, we decided to produce this book; which contains the testimonies ofthe scientists who participated in the discussions exactly as they appeared in the videotape, without any alterations whatsoever [please read Second Edition Preface for a summary of changes - Ed.]. : This book has statements of a scientific nature contained in the Qur’an and other subjects to specialists from other disciplines. Astronomers, zoologists, geologists and specialists in the history of the earth would all have been struck, just as forcibly as medical doctors, by the presence in the Qur’an of highly accurate reflections on natural phenomena.
