Muslim medical contributions were numerous. The innovation of hospitals was one of the greatest achievements of the Muslims in the Middle Ages. They were the first founders of the hospital we know today, preceding others by more than nine centuries. The first Islamic hospital, specializing in leprosy, was established during the period of Al-Walid Ibn-Abdul Malek, the Umayyad Caliph, who ruled from 86 A.H to 96 A.H.
Many hospitals were established in the Islamic world afterward. These hospitals developed a high standard of science and medicine and were considered the first university hospitals in the whole world, whereas the first European hospital was built in Paris nine centuries later.
