The Bahai faith, an offshoot from Islam, also originated in Persia in the 1800's as far as I recall, and it is now a world religion, albeit one of the smaller ones. Unlike Islam, Christianity or Judaism, the Bahai accepts ALL world religions as 100% legitimate expressions of faith, it incorporates all their holy books in its teaching, and it honours all their prophets.

That is very wise on the part of the Bahais. Were others to show an equal degree of wisdom, there would be no more religious wars.
