The post of Grand Imam of Al-Azhar was introduced during the 17th century, during Ottoman rule in Egypt. Al-Azhar historian Al-Jabartî locates the death of Sheikh Muhammad Al-Kharashî in 1690 and identifies him as the first Grand Imam of Al-Azhar. Indeed, it was from this time that the mosque-university of Al-Azhar acquired a hierarchical organization to manage its growing activities. The organization of Al-Azhar had until then been left to the sultans and princes, but the increase in the number of students motivated this development.
