Estimates of the number of Sufis in Egypt include at least a third of the adult male Muslim population in Egypt, being members of a Sufi order; fifteen million of the country's roughly 80 million citizens "claim" Sufism "as a practice", still others say that while 15 million are registered as Sufis, "the true figure is likely to be higher". Participation at the festivals (moulids) the Sufi orders organize, is perhaps twice that (and includes women and children). The moulids are a major manifestation of Sufi Islam in Egypt, and are held in honor of holy men and women (In Egypt the term Moulid is not reserved for Muslim festivals and may be in honor of Christian, and until recently Jewish holy men). Sufi Muslim moulids not only venerate the prophet Muhammad and his descendants (such as Hussein, the second son of the fourth Caliph Ali whose moulid in Cairo can draws crowds of more than a million people), but founders of Sufi orders, down to dozens of lesser-known sheikhs celebrated mostly in remote rural communities. The largest moulid in Egypt takes place in Tanta, which draws an even larger number of pilgrims than hajj in Mecca. As many as three million Egyptians and other Arabs gather there every October to celebrate the life of Sayid Ahmad al-Badawi, a thirteenth-century Sufi leader. According to the Egyptian Ministry of Awqaf (Islamic charity), there are officially more than forty such annual commemorations, and the Sufi Council in Egypt lists eighty other festivals for lesser-known founders of Sufi orders.
