All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
In principle, it is permissible for a Muslim to buy from Jews, Christians, polytheists and all other non-Muslims or to sell them goods within the limits of the Sharee’ah. However, any involvement in Riba (interest and/or usury), selling pork and the like are forbidden. Therefore, there is no harm to purchase their food, drinks, garments, means of transport, etc. as long as they do not contain any prohibition of the Islamic Sharee’ah.
Allaah Knows best.
