Muhammad ibn Zakariya al-Razi, Hunayn ibn Ishaq, Ibn Sina (Avicenna), Ali ibn Isa al-Kahhal, Ibn al-Nafis, and Mir Mu’min Husayni Tunikabuni were all students that trained at Islamic hospitals in order to advance their knowledge in the medical field. These students were key players in the advancement of bimaristans because of contributions to Islamic Medicine from their observations and writings. Muhammad ibn Zakariya al-Razi was an Islam philosopher, physician, and alchemist, who trained well in the Greek science and is known for his "Comprehensive Book of Medicine." Hunayn ibn Ishaq was viewed as a mediator between Greek sciences and Arabs due to his translations of multiple documents that were tremendously important. Hunayn ibn Ishaq was also an optometrist. Avicenna was a physician as well as a government official. The "Canon of Medicine" constructed by Avicenna systemized medicine logically. Like Hunayn ibn Ishaq, Ali ibn Isa al-Kahhal was also an optometrist, who classified more than one hundred diseases of the eyes. Ibn al-Nafis was also a physician and an author, most known for his commentary on pulmonary circulation. Lastly, Mir Mu’min Husayni Tunikabuni focused on how yogic breath control can control the humours. While all of these people did many different things, they all contributed to advancements in medicine.
