What is the ruling on a school canteen whose profits are divided between the contributing students and the school's interests without equal distribution?

The questioner : Your Eminence, there is a school canteen with investors from among the students and the school. However, the profits amount to approximately one to five riyals. The person in charge of the canteen is forced to buy some school supplies, such as photocopying paper and the like. The profits are not divided equally between the students and the school; the student is given two riyals for every one riyal, and the rest goes to the school. What is the ruling on this?

The Shaykh : In other words, the summary of the question is: The school canteen divides its profits between the contributing students and the school's interests. If this is with the consent of the students, there is no harm, provided they are adults of sound mind. If they are below the age of maturity, the reference is to their guardians. If the guardians say, "Some of the profit is sufficient for us, and the rest is for the school's benefit," then there is no harm. Permission is necessary. Then, if it is well-known among people that the canteen divides its profits between the investors and the school's interests, then no specific permission is needed; what is well-known is sufficient. Yes, please proceed.
