It is not fair to say that Adam Smith et. al. got their ideas from the Islamic world and not from Protestant reforms. Surely some inspiration came from both. Further in the absence of Arab advances, we can't tell what the would would have looked like. It certainly wouldn't look like our current world, but there are a ton of possible worlds out there. You can't predict alternative histories retrospectively with any certainty. Nassim Taleb expounds on this in his latest book "Antifragile". He points out that while Adam Smith certainly drew inspiration from Arab philosophers (Al Ghazali in particular), we can't say how the world would look today without that particular intersection having happened.
