No, I do not believe so. I think that if someone prays for death and expects to die, then it's likely that they will have to wait for a long time. I've never really believed in religion at all, I think that there's nothing to pray to. Many people likely believe in religion as they are in denial of the true meaningless nature of life. They don't want to accept that we exist all for no purpose. I think that if someone wants to die sometime soon they will have to take action in order to achieve that rather than waiting for other causes to give them the permanent relief from suffering that they so desperately want.
