The most famous Muslim scientists/ philosophers/ Astronomers/ Chemists/ Mathematicians, Doctors, Poets etc were all Persian/ Iranian. From Hafiz to Romi to Firdausi, Khwarizmi, Bokhari to Razi, Avicenna to a dozen others. All Iranians, and household personalities in Iran today. No need to blow our trumpet here but this is a fact. Qoran's first tafseer and the compilation of all Hadees were done by Persians. So was the Moghal empire in India, backed by Persia. All the Royals in the courts were Persian aristocrats. Everyone in Moghal empire spoke Persian. The architects of almost all Moghal monuments were Iranian architects, including the Taj Mahal. The Greeks and Romans took a lot of this knowledge to Europe.
Now I guess its fashionable to associate the Muslim world with this too.....lol
