SHAFAQNA – The Grand Ayatollah Safi answered a question about going to fortune tellers and writers of amulets (those who write Duas).
Question: What is the ruling about going to fortune tellers and writers of amulets?
The Grand Ayatollah Safi: There is no problem in writing Duas with authentic proofs from infallibles (AS) and earning money for it. But going to writers of Duas who narrate or write from unreliable religious sources is not allowed and these earnings are not right (as they earn without doing a positive work) and are Haram.
