What is the ruling on placing boards in mosques with the names of the circles and the names of the ideal students, and so on?

Question:
He says: Honorable Shaykh, may Allah grant you success, we are your sons, students of the Qur'an memorization circles. We are putting this question to you, which is that we place boards in the mosques, on which the names of the Companions or scholars are written, and each circle has a name. We also place a board of honor on which the name of the ideal student and the name of his circle are written. What is the ruling on doing this?

Answer:
You have turned the mosque into a museum. This has become a museum. It is not permissible to write in the mosques or to hang any writings in the mosques, because this distracts the worshippers. The scholars have disliked decorating the mosques and writing in them, because this distracts the worshippers and because it is part of the decoration of the mosques that is prohibited. So nothing is to be hung in the mosques. If you want to donate or do something outside the mosque, not inside the mosque, you may hang boards or the name of so-and-so's circle, so-and-so's circle. All praise is due to Allah, it is all a Qur'an circle. What is the reason for dividing them into Abu Bakr's circle, this one's circle? Perhaps this will lead to factionalism, and then factionalism will occur among the students. So leave these matters and these formalities. Yes.
