11 Question: What about the leather products made in a European country, if we are unaware of the source of that leather? It is said that some European countries import cheap leather from Muslim countries and then use it for manufacturing various products. Can we consider such leather pure? Are we allowed to say salat in them? Can such a weak probability [about it originating from a Muslim country] be given any credence?
