As I wrote Arabs conquered like 95% of the conquered lands by Muslims and those that were not conquered directly by Arabs, Arabs were the first one to propagandize Islam to those lands as explained in detail in post 331.
The new territory that they conquered to the Muslim world is tiny Kosovo, half of Bosnia and the Turkish minority, less than 1 million, in Bulgaria. Those are the lands that remain Muslim. Other than that tiny Balkans (not even all of it) and Greece. That's the new territory that Ottomans conquered in 400 years (!) of history!
Even Arabs were at the gates of Constantinople (several times in fact) when real Turks were still roaming the steppe leaving nothing of worth. Not even a single World UNESCO Heritage Site. Those sieges occurred at a time when the Byzantine was still a powerful empire and not a joke like it was 600 years ago.

All this while controlling a vastly bigger empire and caliphate than the Ottomans did.
Have you ever heard about science and Turks in pre-Islamic times being mentioned in the same sentence or even any heritage? Never. There is a reason why Turkish scientists, poets and scholars (well-known Islamic ones) can be counted on 2 hands. Also there is a reason why there is almost no Turkic heritage in Central Asia. I don't think there is a single World UNESCO Heritage Site in Central Asia (non-nature one) that is a testimony of anything that they have left to mankind. Not even a single continuously inhabited city. Compare that with World UNESCO Heritage Sites such as Petra (voted as the new 7 wonder of the world), Mada'in Saleh, Hatra, Palmyra, Bosra, Avdat etc. just built by Nabatean Arabs from Hijaz alone.

Jane Taylor, a writer, describes them as "one of the most gifted peoples of the ancient world".

Islamic Golden Age and all. Enough said.
