Spiritual purity in the afterlife

وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ سَنُدْخِلُهُمْ جَنَّـٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ خَـٰلِدِينَ فِيهَآ أَبَدًا ۖ لَّهُمْ فِيهَآ أَزْوَٰجٌ مُّطَهَّرَةٌ ۖ وَنُدْخِلُهُمْ ظِلًّا ظَلِيلًا

But those who believe and do righteous deeds - We will admit them to gardens beneath which rivers flow, wherein they abide forever. For them therein are purified spouses, and We will admit them to deepening shade.
