Also relating to this, what about praying in masjids funded and run by wahabis (including deobandis)? I have heard from sunni shuyukh that we should avoid prarying in wahabi and shi'a mosques.
Assalamu alaikum, just wondering, is there anything from the scholars regarding prayer in mosques which have been constructed by money given from either non-muslims, openly sinful muslims, or apostates? I ask because like i know in Afghanistan that the Americans have funded constructions for mosques and also in the past you had people like Saddam Hussein pay for mosques to be constructed in other countries, including UK.
