Islamic conquest did not expel people from their lands nor did it even force them to change their religion. It especially didn't try to kill everyone who wasn't of some Arab "Ubermensch" race like the Zionists. It also wasn't exploiting captured countires as a colony like the British do, instead it was nice to people so they assimilated.

There's still a ton of Christians and Jews living in Arab countries. The Muslims were well known to be far better and accepting to the Jews than the Europeans.
