Khamenei and I had been cell mates together in 1974 at the Komiteh Moshtarak, a security prison used under the Shah, whom we had both opposed. This is a story I tell, along with others, in my memoir Letters to My Torturer.
Our friendship began when the prison guard opened the door to a cell and threw me in. I made myself stand up, removed the jacket from my head and put on my glasses. I saw a man, extremely thin, bespectacled, with a long black beard. He was seated on a pile of black blankets. I realized he was a cleric because he was wearing a cloak, which he had made out of his prison uniform. He stood up, smiled a pleasant smile, stretched out his hand, and introduced himself: “Sayyed Ali Khamenei. Welcome!”
