hope you are in the best of Iman and health, how would you start a businees the halal way without using any loans,etc? what did the Prophet :saws1: say about this and how did he :saws1: trade amongst the muslims and the non-muslims?
Muhammad ibn Abdullah was known as success trader before he becomes Rasulullah (saw). Actually he was not capital owner but he sold goods that owned by Khadija (ra) and got profit sharing. After he becomes Rasulullah (saw) he did not do trading again. But there is no any prohibition on trading between Muslims and non-Muslims. Trading is "muamalah" (a relationship between human and human), not "Ibadah" (worship or relationship between human and Allah).
