The ruling on praying behind one who drinks intoxicants or imitates the disbelievers in their customs
Machine translationRead the Arabic original
Q: If a man openly smokes or imitates the disbelievers in his clothing or otherwise, should one pray behind him or not?
A: The prayer is valid behind the person mentioned, provided he is a Muslim, according to the stronger of the two opinions of the scholars. However, if it is possible to pray in congregation in the mosques behind someone who is better than him, that is more preferable and safer.
