Answer:
Muslims are having disputes between them, this is their greatest challenge.
many muslims have forgotten the teachings in the Quran, and because of that they aren't really acting as the followers of Muhammad and islam.
Muslims are seen as terrorists. The media is portraying a wrong view of muslims and islam in the world. The world is judging islam by the Al-Qaeda and the ISIS.
like Dr. Zakir Naik said:
'' if a person driving a ferrari gets into an accident, will you say its the car's
fault or the driver's?''
obviously it's the driver's fault, since he didn't know how to drive. That's what's happening with Islam. It's a beautiful religion of peace but the muslims aren't acting accordingly. They're so focused on maintaining a modern image that they can't care about what's happening to their religion.
If they'd act out accordingly to the teachings of Quran, than they'll get out of this situation they are in.
They can stand up to this racism, hatred, and miscreated image of themselves if they fix themselves first.
