﴿ جَزَآؤُهُمْ عِندَ رَبِّهِمْ جَنَّٰتُ عَدْنٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَآ أَبَدًۭا ۖ رَّضِىَ ٱللَّهُ عَنْهُمْ وَرَضُوا۟ عَنْهُ ۚ ذَٰلِكَ لِمَنْ خَشِىَ رَبَّهُۥ ﴾

“Their reward [awaits them] with God: gardens of perpetual bliss, through which running waters flow, therein to abide beyond the count of time; well-pleased is God with them, and well-pleased are they with Him: all this awaits him who of his Sustainer stands in awe!.”

Their reward with their Lord will be Gardens of Eden as a residence underneath which rivers flow wherein they shall abide forever. God is pleased with them because of their obedience of Him and they are pleased with Him because of His reward. That is the reward for him who fears his Lord for him who fears His punishment and hence desists from disobeying Him exalted be He.
