Machine translationRead the Arabic original
Question:
He says: Honorable Shaykh, may Allah grant you success, sometimes we pray behind some of the expatriate communities, and we do not know about their belief. Is it obligatory for us to ask them about their belief, knowing that we may be travelers?
Answer:
No, they are not required to ask if they find Muslims praying, then pray with them; your prayer is valid, if Allah wills, unless you know that his prayer is not valid because he is committing one of the nullifiers of Islam. If you know this, then [ask]. But if you do not know, then hold the best opinion, pray with the Muslims, and do not ask. The text of Surat al-Baqarah states this.
