context: The first institute for madrassa education was at the house of Zaid-bin-Arkam at the foot of Mount Safa - where the Prophet (s) himself was a teacher and student, and some of his followers were non-Muslim. After the emigration, Madrasah Ahl-e-Sufa was set up in front of the new Prophet at the mosque in Medina. The teacher was Ubada-ibn Sammit and Abu Hurairah Mu'az-ibn Jabal Gifari was one of the students. The madrasas of the time were in the curriculum, the Quran, Hadith, Farage, first aid, genealogy, Tajiks, etc. Also included were courses in horse riding, warfare, manuscript education, body exercises. The first phase of madrassa education was considered for a period of about one hundred years, from the first day of the prophets to the first part of the Umayyad dynasty. [1]
