One example of the events foretold in the Quran is the victory of the Romans over the Persians within three to nine years after the Romans were defeated by the Persians.

Let us see what history tells us about these wars.  A book entitled History of the Byzantine State says that the Roman army was badly defeated at Antioch in 613, and as a result, the Persians swiftly pushed forward on all fronts.1  At that time, it was hard to imagine that the Romans would defeat the Persians, but the Quran foretold that the Romans would be victorious within three to nine years.  In 622, nine years after the Romans’ defeat, the two forces (Romans and Persians) met on Armenian soil, and the result was the decisive victory of the Romans over the Persians, for the first time after the Romans’ defeat in 613. 2  The prophecy was fulfilled just as God has said in the Quran.

There are also many other verses in the Quran and sayings of the Prophet Muhammad  that mention future events which later came to pass.
