Muslims were the leading nation of the world for hundreds of years under Islamic Caliphate which ruled 3 continents, dozens of countries and hundreds of ethnicities.
During these years Muslims had the best educational institutes, best libraries, best hospitals and best military. But what are the greatest things which we can be proud of even today?
Learning started with the first human being in the world but the first proper University of the world was established by a Muslim woman Fatima al-Firhi in 859 which is still operational and is known as University of Fez.
To understand the impact of this act you need to know that Britain allowed women to enroll in university in 1878.
Hospitals the way we see them with proper buildings, wards and teaching centers is also a thing which was introduced by Muslims.
In 872 Muslims established the first proper hospital in Cairo which was called Ahmad ibn Tulun Hospital. The hospital provided free services to anyone, and soon such hospitals spread all over the Muslim world.
