جَزَآؤُهُمْ عِندَ رَبِّهِمْ جَنَّٰتُ عَدْنٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَآ أَبَدًۭا ۖ رَّضِىَ ٱللَّهُ عَنْهُمْ وَرَضُوا۟ عَنْهُ ۚ ذَٰلِكَ لِمَنْ خَشِىَ رَبَّهُۥ
Their reward is with their Lord: Gardens of Eden underneath which rivers flow, wherein they dwell for ever. Allah hath pleasure in them and they have pleasure in Him. This is (in store) for him who feareth his Lord.
