Ahle - Zimmi abiding to islamic laws of trade

Question

Is it necessary for the Ahle - Zimmi (those Kuffaar living in a Muslim country) to abide to Islamic laws of trade, in so far as it being Faasid or valid etc. for them?

zd · Answer

They will be treated in laws of trade as the Muslimeen are, except for pig and wine. Their dealings in wine will be like a Muslim dealing in juice and their dealings in pig will be like a Muslims’ dealing in sheep (Kitaabul Buyoo).
