Yes my brother, it was the golden age of Islam, the Islam of science and knowledge, in Morocco we say that at that time to learn the sciences you had to learn Arabic, like today we have to learn english.
In Andalusia alone, for 600 years Muslim scholars had revolutionized the sciences: medicine, geography, astronomy ... the era of Ibn Batouta, Ibn Roshd, Ibn Khaldoun and many others, Tarik Ibn Zayad who conquered the Muslim Spain. At that time Christians came to learn science from Muslims, and relied on that to launch the European Renaissance, which heralded the end of the Islamic golden age, the reconquista, then colonization. History speaks....
When we unfortunately see today the state of the Muslim world. we want to cry.
