Muslims from the Bohra community listen to a Holy Quran recitation as they join hundreds of Muslims from different sects in Nairobi, Kenya, Sunday, March 11, 2007, to mark Arbaeen, one of the holiest days in their religious calendar. Arbaeen marks the end of the forty-day mourning period after the anniversary of the 7th century martyrdom of Iman Hussein, the Prophet Muhammad's grandson. (Sayyid Azim/AP Photo)
