Machine translationRead the Arabic original
Question:
Some people pray behind one who commits major shirk, saying: "He is ignorant, and he is a Muslim," and they pray behind him?
Answer:
If it is known that he is a mushrik (one who associates partners with Allah) committing major shirk, the prayer behind him is not valid by the consensus of the Muslims. Indeed, the prayer behind a mushrik is not valid by the consensus of the Muslims, if it is known that he is a mushrik.
Q: Praying behind fortune-tellers?
A: One does not pray behind a fortune-teller; because the fortune-teller may be a mushrik, and he may agree with the sorcerers and astrologers, and he may agree with others; so he becomes like them.
