How do we know Islam isthe truth?

Ans: 1- It is the only religion that holds Allah as One, Unique, and Perfect.
2- It is the only religion that believes in the sole worship of Allah,
not Jesus, not an idol, and not an angel, only Allah.
3- The Quran does not contain contradictions.
4- The Quran contains scientific facts, which are 1300 years ahead of
theirtime. The Quran, while revealed 1400 years ago contains
scientific facts, which are only now being discovered. It is not in
contradiction to science.
5- Allah has challenged the world to produce the like of the Quran.
And He says they won't be able to.
6- Prophet Muhammad (peace be upon him) wasthe most influential man in
history. In the book"The 100 most influential men in History", written
by non-Muslim, the Prophet Muhammad (peace be upon him) was#1. Prophet
Jesus (peace be upon him) was #3. It should be noted that even the
Prophet Jesus (peace be upon him) wasa prophet sent by Allah. Would
Allah allow a false prophet to be so successful? No. Even the Bible
refers to this in Deuteronomy 18:19. A false prophet would die!!! Yet
Prophet Muhammad (peace be upon him) did not die till he completely
conveyed, and taught Allah's religion.
7- He had many prophecies, and all of his prophecies have come true,
or are still coming true.
