A teacher asks students to bring inexpensive items for educational purposes and guidance, and assigns grades for them!!

Question:
He says: Honorable Shaykh, may Allah grant you success. This is a teacher asking, and she says: I am a teacher, and I ask the students to bring simple, inexpensive items for those who wish to do so, to explain them and to clarify concepts. I give the student a grade for what she brings, and I keep these items in the school so they remain for future years. Then there is a surplus left over. Is it permissible for me to distribute it among my colleagues, my neighbors, and my relatives?

Answer:
The male and female teachers are required to perform the duty for which they were appointed, which is teaching. As for collecting money, that is not their concern. That is not their concern, and they were not appointed for it. They also bear a trust in their souls. So the teacher, or the school, is limited to the work for which he was appointed, and he performs it. Yes.
