Koran, the sacred book of the Muslims, has hinted at a number of scientific truths that have been uncovered by the technology of the 20th century. Of course Koran is not a book of science.

These facts could not have been known at the time of Koran revelation 1,400 years ago. You will see some of these truths in this web page.
