Becoming powerful in his own right, and having the power of life and death over others, didn't benefit him?
The belief that he was accountable only to Allah - who, effectively, only spoke through him - didn't benefit him?
My points?
1. Falsification has a way of becoming irrelevant when you ignore inconvenient propositions rather than falsify them.
2. Where Zakir Naik doesn't
lie outright, his field of vision is conveniently narrow..
