In the name of Allah, The Most Beneficent, The Most Merciful.
I have just watched a great video that explains Islam in a nutshell. Trust me, it is very hard to explain what a faith is about in just under 15 minutes. CrashCourse did so well in not only explaining what the religion is about but also how the religion came about. The video even explained an aspect of Islam that I personally find difficult to explain to non-Muslims, in terms of how we accept or reject scriptures by examining the chain of narrations. Seriously, have a watch if you have not. It takes less than 15 minutes.
