Is it permissible to borrow money from a medical center for the purpose of trade and profit, then return it when available?

There is no objection to one partner borrowing from the company's funds with the permission of their co-partner. This is similar to the ruling on one partner lending something from the company's funds to another. However, if it is established among the partners that loans are for financial distress or need, then borrowing for the purpose of trade and profit is not permissible except after explicitly informing the partners. This is because "whoever is given something based on the assumption of a characteristic, but is in reality otherwise, and if the giver had known, they would not have given, does not own what they take."
