Assalamu-alaykum
1.My question is with regards to investments. Is it permissible to invest with someone in a clothing shop business (or any other halaal business) where you receive a pre agreed set amount of the profit on a monthly basis until the time when the business is no longer doing well and the owner returns your original investment (and thus stops giving you any of the profits)?
2. and is the money you originally invested which has been returned to you still permissible for you to use?
Jazakallah
