Leading the prayer of one who prays on a chair while the congregation stands

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: We have an imam in our neighborhood mosque who is currently praying on a chair because of his old age. We have an imam in our neighborhood mosque who is currently praying on a chair because of his old age. He is leading the prayer, and the people behind him are praying standing.

Answer:
This is not permissible. This imam is ignorant; how can he lead people in prayer while he is on a chair? Also, his ailment is permanent and not expected to end. Take note, the regular imam of the neighborhood: if his ailment is expected to end and he prays sitting, the people pray behind him sitting. If he is the regular imam of the neighborhood and his ailment is expected to end, and he prays sitting, they pray sitting. But if he leads them on a chair and continues in this state, and his ailment is not expected to end, this is not permissible. Who is issuing the ruling on this? It is obligatory for the mosque affairs department to prevent him from leading the prayer. Yes.
