Question

Describe the Rise of Islam during this time period, the origin and principles of the Quran, and why Islam was so successful in its expansion.

Answer 1

You mean in the present?

I think one of the reasons why Islam is rising is people are getting aware of the things a true religion can have, also Muslims are all around the world in the present so they are impressing many people by the teachings of Islam and from their behaviour.

I only had these opinions of mine but I really think they are true. You can change the wordings though.
