Many are rewarded before being born, but when they are born alive, they do not know or they deny the reward that they themselves are! Moreover, they do not enjoy the reward that they themselves are! And even though they may know not that they deny the reward, the reward they do deny! And because of denying the reward, thus they stop being themselves and for stop being themselves, thus they will stop from being or from living!
Thus, in truth, the reward always was one and always one will be the reward while one lives because the reward is life, one alive as one was born alive!
