I attended a funeral today for my wife's aunt. After the janazah prayer, I found out that the person performing the janazah prayer was not muslim. He was an Ahmadi belonging to the sect who says Mirza Gulam was a prophet. I personally feel that the janazah was not valid, but there were a lot of muslims in the congregation, who paid little attention to the fact that the leader was not muslim. Should my family and I re-pray the janazah?
Praise be to Allaah.
Yes, you have to repeat the funeral prayer, because this imaam behind whom you prayed is a believer in a kaafir doctrine which puts him beyond the pale of Islam. We ask Allaah to show mercy to your deceased loved one..
