Sufism is the mystical element of Islam, with sufis first coming to Sudan in the sixteenth century.
Every Friday at the Hamid el-Nil mosque in Omdurman, groups of sufis come together to engage in the dhikr. Come Mawlid, the birthday of the Prophet Mohamed (and a celebration which is seen as haram in certain groups of Muslims), thousands of sufis come together across the capital to hear stories about the prophet, pray and dance together.
