Because the Koran is quite clear when it says that you'll be "a new creation in paradise," and that you will be "recreated in a form unknown to you," which seems to me a far more appealing prospect than a virgin.
Jer Kuran je dosta jasan kad kaže da ćete biti "nova kreacija u raju" i da ćete biti "ponovno stvoreni u vama nepoznat oblik", što mi se čini kao daleko primamljivo očekivanje od djevice.
