We know that after entering jannat, a man will get whatever he wishes. Then if a man wants 100 billion hoor and 100 million wives, will he get 100 billion hoor and 100 million wives in jannat?
This is transgression! One would get what no eye has seen, no ear has heard of and no heart has ever imagined.
Going into such details with such numbers is transgression. One should strive to make it to paradise in the first place before thinking of such things!
