On November 5, 1986, although he was still a member of the parliament, was arrested by Ministry of Intelligence and National Security and passed 2 years of his life in the jail.

[citation needed] His father, Abol-Ghasem Kashani was a prominent Twelver Shia Muslim cleric and former chairman of the parliament.

[3] According to Trita Parsi's Treacherous Alliance, in early 1980 Kashani visited Israel to discuss arms sales and military cooperation regarding Iraq's Osirak nuclear reactor.

This resulted in an arms deal (a shipment of F4 Phantom tyres and other weapons, the beginning of Operation Seashell) and the Ayatollah Khomeini's permission for large numbers of Iranian Jews to leave Iran, including thousands who left via bus to Pakistan and then via air to Austria, before heading to the US or Israel.

[4] Kashani was a deputy for Natanz when he was one of several arrested in 1986 on charges of conspiring with Mehdi Hashemi.
