The Ruling on Praying Behind an Imam of Unknown Creed
Machine translationRead the Arabic original
Question:
Honorable Shaykh, a person is praying with us whose creed we do not know, but we know that the rulers of the land are strict with him; they do not pray with him, nor do they ask about his creed.
Answer:
The default for a Muslim, if Allah wills, is that he is good, as long as nothing has appeared to you regarding him and you do not know anything about him. The default for a Muslim is goodness, and there is no harm in praying behind him. However, if something appears to you or you learn something about him, do not pray behind him. Yes.
