A constant stream of people come to the mosque to pay homage at the tomb of Amadou Bamba - a Sufi mystic and founder of the Mouride Brotherhood.

For true believers, says Mr Sene, the path laid down by Bamba is nothing short of “the real practice of Islam”. It is also a path of which many other Muslims in the world strongly disapprove.

“They think we are nothing,” says Mr Sene, referring to many Arab Muslims, whom he says have done much to rid their own countries and east Africa of Sufi traditions.

“They think we are crazy. They think they are superior.”
