Q: I do transport for a company that does packaging for various other companies. I do not know the details of their agreemants. I was given a bag of products from the company as they were moving warehouse. Also the balance of the products were returned to the companies for whom this company offers their services to. Can I use these products or is it better to return them?
A: You rather find out from the concerned companies directly.
And Allah Ta’ala (الله تعالى) knows best.
