Mrs. Pakravan confirms the well-known story that her husband saved Ayatollah Khomeini's life in 1963. He was condemned to death and General Pakravan was upset by that. Pakravan felt that Khomeini's execution would anger the common people of Iran. He knew that the population of the country is not its elite. He presented his argument to the shah. Once he had convinced the shah to allow him to find a way out, he called on Ayatollah Mohammad-Kazem Shariatmadari, one of the senior religious leaders of Iran, and asked for his help. Ayatollah Shariatmadari suggested that Khomeini be made a grand ayatollah. So, they made a religious decree which was taken by General Pakravan and Seyyed Jalal Tehrani to the Shah.
