In Benazir Bhutto's final work, written just before her life came to a tragic and untimely end, she notes:
"Shias offer Fataha, the Muslim prayer, at the burial places of imams and their descendants. Many Shiites go on pilgrimages to the burial places of important imams to pray to God that in the name of the beloved Imam Hussain they may be blessed to overcome their troubles."
It should be noted, by her own recounting of the Bhutto family's religious profile, that Benazir's father was Sunni and her mother was Shia.
