If it weren't for the Turks, the Crusaders and Mongols would have come crush your Arabs, what kind of fairy tales are you telling ?
When the Turks entered Anatolia en masse in the 11th century (after the Battle of Malazgirt in 1071), there was almost no Muslim population in the Anatolia
Before the arrival of the Turks, Anatolia was entirely under the rule of the Christian Byzantine Empire
The Turks also Islamized the Balkans
The Crusaders never managed that (despite all of Europe uniting in this endeavor) and their presence covered less than 2% of the total Arab landmass.
Mongols barely destroyed/killed any Arabs outside of Baghdad.
Most of the people they killed were Central Asian Turks, Persians and East Asians.

I already wrote that the only region of the Muslim world that was not made Muslim by Arabs was West Balkans but that is a tiny region of the Muslim world and today only encompasses half of Bosnia (1.5 million people) and some 2-3 million Albanians.
Islam in Greece was spread by Arabs first (Emirate of Crete) and other regions of Greece.

And it is completely nonsense to claim that there were no Muslims in Anatolia before Seljuks? Did you forget 400 years of mostly Arab Muslim rule of South and East Anatolia?
Even many Turkish cities in South and East Anatolia are of Arab origin.
Diyarbakir (Turkish Kurdish capital of Anatolia) derives from an ancient Arab tribe (Banu Bakr) that settled the region.

Why do you think that were many Muslim scholars and scientists (most Arab in origin) born in Anatolia before the Seljuks?
Don't confuse West Anatolia (Byzantine heartland) with South and East Anatolia. Very different histories. Even to this day the regions are quite distinct.
One is literally next door to the Arab world (Syria and Iraq) (South and East Anatolia) home to ancient Arab communities and the other region (West Anatolia) is next to Greece and Bulgaria.
All of Anatolia first became majority Muslim 1-2 centuries after Ottoman consolidation (some 500 years ago or so).
Similar to Pakistan itself, Sindh was Muslim long before the North became Muslim. To this day you still have some Pagans in North Pakistan due to geographic isolation.
