A person suffering from a mental illness who hanged himself, and the mosque imam refused to pray over him; is his action correct?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: A person was suffering from a mental illness and hanged himself until he died. When we brought him to be prayed over, the imam did not pray. He says: A person was suffering from a mental illness and hanged himself until death. When we came to pray over him, the imam of the mosque did not pray over him and said that the general public should pray over him. The caretaker of the mosque prayed over him. So, is it the case that no one who kills himself is prayed over except by the general public?

Answer:
This imam is ignorant. The one who killed himself is, first of all, a Muslim, and it is obligatory to pray over a Muslim. A Muslim who commits a major sin among the major sins does not become a disbeliever because of it. He has the right to be prayed over; this is obligatory. The second point is that the one who does not pray over a person who killed himself is the Grand Imam, not the imam of the mosque. The Grand Imam is the Sultan, because this serves as a deterrent for them and those like them. The Grand Imam is the one who hears this. We consider this person to be the imam of the mosque. It is not permissible for a person to do things out of ignorance and lack of knowledge. Yes. Also, this person says he was suffering from a mental illness. He was suffering from a mental illness. He did not do this with thought or intellect. Yes.
