The human body has a biological dimension of development as well and the Quran has expressly explained its different biological stages. The Quranic verses clearly underscore the fact that man has been created from a single cell. All these facts were anticipated by the Quran fourteen centuries ago when the modern scientific research did not enjoy even an embryonic existence. As a matter of fact, the systematic explanation and analysis furnished by the Qur'an has not only made current scientific research possible but also added incalculably to its credibility, otherwise the modern scientists would be floundering in the dark of chaos and confusion.
