Reward in this world and the next that a person merits by his good deeds in this world. This takes two forms: reward in this world alone and reward in the next world alone. Sometimes a person merits both on account of a single deed. This matter was not explained to us in detail. Rather, the Creator promised His people general reward for general observance and did not state specific reward for respective acts of service in this world as he did in regard to punishment for transgression. But of reward and punishment in the next world, the Prophet has told us nothing in his book for several reasons. One of these is that the form of the soul apart from the body is unknown to us, still less do we know what brings it delight in that state or causes it to suffer pg 437
