On this day, the 17^th of December, in the year of 1267, the Friday prayers were held for the first time in al-Azhar Mosque in Cairo during the reign of Sulṭān al-Ẓāher Beybers, after nearly a century of the mosque being closed. Al-Azhar Mosque had been neglected during the reign of the Ayyubid Dynasty in Egypt, and Judge Ṣadr el-Dīn Bin Dirbās had warned against praying in it. So, how many times has al-Azhar Mosque been closed?
