Adherence to a Sufi order has long been standard for both professors and students in the al-Azhar mosque and university system. Although al-Azhar is not monolithic, its identity has been strongly associated with Sufism. The current Shaykh al-Azhar (rector of the school), Ahmed el-Tayeb, is a hereditary Sufi shaykh from Upper Egypt who has recently expressed his support for the formation of a world Sufi league; the former Grand Mufti of Egypt and senior al-Azhar scholar Ali Gomaa is also a highly respected Sufi master.[36]
