جَزَاءً مِّن رَّبِّكَ عَطَاءً حِسَابًا (36)
(78:36) a recompense from your Lord and an ample reward *22
*22) "A reward and sufficient gift": that is, they will not only be given their due rewards which they will deserve for their good deeds, but over and above these they will be given additional and sufficient gifts and prizes as well. Contrary to this, in respect of the dwellers of Hell it has been said: "They will be recompensed fully for their misdeeds." That is, they will neither be punished less than what they will deserve for their crimes nor more. This theme has been explained at length at many places in the Qur'an, for example, see Yunus: 26-27, An-Naml: 89-90, Al-Qasas: 84, Saba: 33-38, Al-Mu'min: 40.
