Ruling on Compelling Students to Pay Amounts to Honor the Winners

Question:
These are girls' schools, and each school sent two competitors in the Qur'an. They imposed a condition on all the schools to pay one hundred and fifty riyals from each school. What is the ruling on this action?

Answer:
What is it for?
Q: They say they are buying gifts for the top students.
The Shaykh: It is not valid, except for what is donated voluntarily. Compulsion: they must not be compelled.
Q: Are they being compelled?
The Shaykh: No, no. If it is a voluntary donation to encourage the top students, as a means of encouragement and cooperation, without compulsion.
Q: What is its ruling?
The Shaykh: This is not permissible. It is not permissible to compel them. No one has the right to compel the female students to do this. Rather, one should encourage voluntary donations to encourage the girls who excel in memorizing the Qur'an.
Q: Is the prohibition due to the compulsion?
The Shaykh: Yes. If they donate voluntarily, there is no harm, if they donate to encourage the memorizers or the top students in memorization.
