After the 1977 death of Ali Shariati (an Islamic reformist and political revolutionary author/academic/philosopher who greatly assisted the Islamic revival among young educated Iranians), Khomeini became the most influential leader of the opposition to the Shah. Adding to his mystique was the circulation among Iranians in the 1970s of an old Shia saying attributed to the Imam Musa al-Kadhem. Prior to his death in 799, al-Kadhem was said to have prophesied that "A man will come out from Qom and he will summon people to the right path". In late 1978, a rumour swept the country that Khomeini's face could be seen in the full moon. Millions of people were said to have seen it and the event was celebrated in thousands of mosques. He was perceived by many Iranians as the spiritual as well as political leader of the revolt. Additionally, the episode with Khomeini's face in the moon showed that in late 1978 he was increasingly regarded as a messianic figure in Iran.
