Is it permissible for a young man to pray on a chair in the mosque without an excuse?

Question:
We ask a lot about the chairs, Honorable Shaykh. Some are placed in front and some in back, and especially now the young men have started using these chairs in the mosque without need.

Answer:
It is not permissible to use them without need. They are only for those who have an excuse, such as those who cannot stand or cannot prostrate. So they are for those with an excuse only. As for their placement, it is according to need. According to need, if one needs a wider space or a smaller space, it is according to need. And the smaller the chair is, according to the need, the better it is. Yes.
