Iran has begun unprecedented funeral and burial arrangements for its former Supreme Leader Ayatollah Ali Khamenei, who was killed four months ago in a joint U.S.-Israel attack. The six-day program spans five cities in Iran and Iraq, with Tehran expecting between 10 and 20 million participants. During this period, extensive discussions are taking place about Khamenei’s life and teachings.

Khamenei’s autobiography, “Cell Number 14,” provides insight into his early years as an imam. He began leading prayers at the small Imam Hasan Mosque in Mashhad before moving to the larger Keramat Mosque, which became a hub for students and merchants. Authorities later barred him from leading prayers there due to his growing popularity. He then returned to Imam Hasan Mosque, delivering sermons after evening prayers.

The book also recounts his time in Tehran in 1966, his exile in Iranshahr where he led prayers at Al-Rasul Mosque, and his imprisonment in Mashhad’s military prison, where his religious influence led guards to restrict his activities.
