Islam is a universal religion with 1.7 billion followers worldwide.

Read the Holy Quran, all the answers of this world is there.

You know something, it's really weird. That belief net website where you answer a whole lot of questions and in the end you're matched up with whatever religion most closely resembles your answers?

I always end up with Orthodox Judaism in first place.
But I always, and I mean ALWAYS end up with Sikhism in second place.

It doesn't get any stranger than that.

P.S. I've been taking that test on belief net.com for about 7 years now.

there is nothing such, indeed Sikhism is completely different from Islam or Hinduism.
but there are a few festivals that Hindu and Sikh people share.
