From the life of Hazrat Umar (ra) bin Khattab
In relation to organising the education system, it is mentioned that Hazrat Umar (ra) greatly improved the education system. He established schools in all the countries [under Muslim rule] wherein the Holy Quran, hadith and fiqh were taught. The companions, who were great scholars were appointed as teachers and overseeing the moral training and a salary was also fixed for those who were appointed as teachers.
