On the afternoon of June 3, 1963, Ashoura, Khomeini delivered a speech at the Feyziyeh School in which he drew parallels between the Umayyad Caliph Yazid I and the Shah.
 He denounced the Shah as a "wretched, miserable man", and warned him that if he did not change his ways the day would come when the people would offer up thanks for his departure from the country.
 In Tehran, a Muharram march of Khomeini supporters estimated at 100,000 marched past the Shah's palace, chanting "Death to the Dictator, death to the dictator!
God save you, Khomeini!
Death to the bloodthirsty enemy!"

Two days later at three o'clock in the morning, security men and commandos descended on Khomeini's home in Qom and arrested him.
They hastily transferred him to the Qasr Prison in Tehran.
