Is it permissible for the borrower to rent out part of the house he obtained from Aramco through a benevolent loan and free land, knowing that the agreement prohibits renting out the property before repaying the loan except with written permission from the company?

The issue is summarized as follows: the land is mortgaged to the company until the loan is repaid. Scholars have differed on the permissibility of the mortgagor leasing the mortgaged property without the permission of the mortgagee. Some have prohibited it, such as Abu Hanifa and Ahmad, while others have permitted it for a period ending before the debt is due, such as Malik and Al-Shafi'i. The company has the right to stipulate to the debtor that he may not lease the house, because leasing weakens the security of the debt, and Muslims are bound by their conditions.
