You will see the wrongdoers fearful of what they have earned, and it will [certainly] befall them. And those who have believed and done righteous deeds will be in lush regions of the gardens [in Paradise] having whatever they will in the presence of their Lord. That is what is the great bounty.
You, O Messenger, will see those who wrong themselves by ascribing partners to Allah and committing sins fearful of the punishment because of the wrongdoing they did. The punishment will inevitably fall on them. Their mere fear that is devoid of repentance will not be of any use to them. Those who have faith in Allah and in His messengers, and do righteous actions will be in contrast to them. They will be enjoying luxury in gardens of Paradise. They will have whatever type of endless bliss they wish for by their Lord. That is the great bounty which no other bounty can come close to.
