Does the one in authority refrain from praying the funeral prayer over all those who commit major sins?

Question:
May Allah reward you. In his second question, he asks: Is it correct that the one in authority does not pray the funeral prayer over those who commit major sins?

Answer:
We understand that he does not pray over all those who commit major sins. He does not pray over one who kills himself, or over one who takes more than his share of the war spoils. Only these two among those who commit major sins: the one who takes more than his share of the war spoils and the one who kills himself.
