He was a secretive figure of the court, reputed for corruption in moral and financial matters. He had the same role as Ernest Prone. When Sorraya, the Shah's second wife came to the court, he made good relations with her and Bakhtiaries.

He had a great role in strengthening the Bahahi's position in the military organs of Pahlavi regime. He played a key role in the appointment of Amir Abbass Hoveida as prime minister. During this period, the number of Bahai's of Iran became threefold.
In 1965, due to the strong attacks of Hojjat-ol-Islam Falsafi to Abdolkarim Ayadi, Mohammad Reza Pahlavi ordered him to leave Iran. He went to Italy for nine months, then he returned and went to Mecca with Shah and wore Ihram (the special garment of pilgrimage) to deceive public opinion.
According to the reports of Iran central bank, on the eve of the Islamic revolution Ayadi, took about 40 million dollars with him to Switzerland and lived there until 1980.
