Not really. Most of their 'scholars' were Christians and Jews, some converted and took 'Arab' names. Christians and Jews made up their bureaucrats, doctors, and even soldiers; Jews were the garrison troops in some major cities captured by the Moors in their invasions of Spain, one of the reasons the Reconquistas didn't trust them and they had to convert or leave. Some of them lied and kept their religions underground, hence the Inquisitions; they were considered a sort of 5th column of traitors, and some of the local Jews aided the Muslims in their conquests of the cities.
In fact one of their alleged 'golden ages' was under three generations of a Persian royal family, that also supported Christian and Jewish scholars and artists. I will look up their names and the years in a while, if anybody is interested. Other than the Persian 'enlightenment' and the one in Spain, mostly by Jews like Maimonides, there was much in between except dark ages, Most people forget Constantinople was still a seat of scholarship up until it fell in 1453, and the West had access to their still significant contributions, often erroneously attributed to 'Muslim scholars' disseminating science and literature in the West.
