Ali Shariati
Also in 1977, the popular and influential modernist Islamist theorist Ali Shariati died under mysterious circumstances. This both angered his followers, who considered him a martyr at the hands of SAVAK, and removed a potential revolutionary rival to Khomeini. Finally, in October Khomeini's son Mostafa died of an alleged heart attack, and his death was also blamed on SAVAK. A subsequent memorial service for Mostafa in Tehran put Khomeini back in the spotlight.
