If Jesus saw fit to forgive Peter after Peter denied Him three times, who are any of us to say whether or not this man has already lost his eternal life?
One more time. I've already addressed this.
Well --- Jesus could forgive him --- but this man will always need to live in fear now --- he might have become a Muslim for a few minutes to save his life, but once a Muslim, always a Muslim --- they can kill him now for trying to change back to Christianity. It's the death penalty for any who try to leave that religion.
