RIYADH US SALIHEEN
Nawa had no academic or scholarly atmosphere and there were no religious academies or institutes where one could earn excellence in religious learning, so his father took him to Damascus, which was considered the center of learning and scholarship, and the students from far and wide gathered there for schooling. Imam Nawawi joined Madrasah Rawahiyah which was affiliated with the Ummvi University. He died in 676 A.H. in Nawa.
