وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ سَنُدْخِلُهُمْ جَنَّٰتٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَآ أَبَدًۭا ۖ لَّهُمْ فِيهَآ أَزْوَٰجٌۭ مُّطَهَّرَةٌۭ ۖ وَنُدْخِلُهُمْ ظِلًّۭا ظَلِيلًا
And as for those who believe and do good works, We shall make them enter Gardens underneath which rivers flow - to dwell therein for ever; there for them are pure companions - and We shall make them enter plenteous shade.
