Hawzah News Agency – Based on Ayatullah Sistani's risalah, there are four ways of obtaining the verdicts of a Mujtahid:
- When a man hears from the Mujtahid himself,
- When the verdict of the Mujtahid is quoted by two just persons,
- When a man hears the verdict from a person whose statement satisfies him,
- By reading the Mujtahid's risalah, provided that, one is satisfied about the correctness of the book.
