Nowadays, Buddhism and Christianity are global religions, though they are relatively minor faiths in their lands of origins. Buddhists are about 1% of South Asia's population, and Christians are about 2% of the population in Israel and Palestine. Both of their religions have most of their adherents outside of their homelands. Is there any way to have Islam do the same thing? That is, for Muslims to be a minority group in Arabia, but still be a widespread religion across the globe? Taking a cue from Buddhism in India, Muslims could be a major religion in Saudi Arabia or the Arabian Peninsula for a long while, but then decline substantially afterwards. In this case, while it still counts if Islam spreads historically through the Rashidun and Umayyad Caliphates before declining in Arabia, I'm looking for something more innovative than that. Bonus points if Islam has the same number of adherents as it does in our world today.
I was inspired by an old map I saw of Crusader states and Mongol khanates being set up in the Middle East, and I was thinking of the effects of a Buddhist/Christian Middle East, but I decided this wasn't too plausible and was a little late as a divergence.
