What is the ruling on renting out a laundry shop for a fixed monthly sum of 6,000 Saudi Riyals, with a sharing of effort and equipment, provided that the worker receives whatever exceeds the agreed-upon amount?

It is permissible to lease a laundry shop, its equipment, or both, to an employee for an agreed-upon sum. This is a valid lease contract according to Sharia. The equipment remains the property of the lessor, who is responsible for its maintenance. It is a trust in the employee's possession, and the employee is not liable for it except in cases of transgression or negligence on their part. The employee is obligated to pay the rent whether they work, profit, or lose. It is also possible for the transaction to be a partnership between the two parties, depending on the nature of the agreement.
