The top of the minaret at the Mosque in Touba.

 

The people you see are Baye Fall---a part of the Mouride Sufi Sect of Islam. They are very different however. They consume a variation of coffee called Café Touba. Their religious practices include NOT praying 5 times a day nor do they fast for Ramadan. They do other work, feeding poor people at the end of the day during Ramadan---also building Mosques---believing that this work opens the door to paradise in lieu of traditional Islamic practices.
