With the proliferation of chairs in mosques, some are observed to be lax regarding the pillar of standing; what is the guidance?

Question:
He says: Honorable Shaykh, may Allah grant you success. It has become widespread in many mosques to place chairs for sitting and praying on them, so many people have become lax regarding the pillar of standing. He says: It has become widespread in our mosques to place chairs for sitting and praying on them. Many people have become lax in that, regarding the pillar of standing. We see them say the takbir of ihram while standing, then complete their prayer on these chairs. What is the ruling on that?

Answer:
This is a trust with them. If he is unable to stand, then sitting on the chair is fine. But if he is able to stand and sits on the chair while he is able to stand, is his prayer valid? This is up to them; they know their own conditions best, and we do not know about them. So they should fear Allah the Exalted and not be lax regarding the pillar of standing when they are able to do it in the obligatory prayer. Yes.
