When Mahr dies I'll pray for him as well, even though privately I'll be glad I never have to hear him again. I actually pray for Mahr right now.
Sorry, I pray for the living, not the dead. There are no second chances. I prayed for Hitchens for a long time, even just the other night when his name was brought up. But he made his bed and now he has to lie in it. I would have rejoiced if he had changed his mind but there is no evidence that he did or had any intention of doing so. As I posted upthread, there are actually very few deathbed conversions in my experience.
AFA, being a ‘liberal’ he attended at least one FR event (someone else posted about meeting him there), and other than religion, he was pretty much a 9/12er according to people esp when it came to Islam.
