Fatwa
Useful information: 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 book of Masae'l, provided that, one is satisfied about the correctness of the book.
