Surah Al-Ma'arij — Ayah 29

وَٱلَّذِينَ هُم مِّنْ عَذَابِ رَبِّهِم مُّشْفِقُونَ

And those who are fearful of the punishment of their Lord -

إِنَّ عَذَابَ رَبِّهِمْ غَيْرُ مَأْمُونٍ

Indeed, the punishment of their Lord is not that from which one is safe -

إِلَّا عَلَىٰٓ أَزْوَٰجِهِمْ أَوْ مَا مَلَكَتْ أَيْمَـٰنُهُمْ فَإِنَّهُمْ غَيْرُ مَلُومِينَ

Except from their wives or those their right hands possess, for indeed, they are not to be blamed -

فَمَنِ ٱبْتَغَىٰ وَرَآءَ ذَٰلِكَ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْعَادُونَ

But whoever seeks beyond that, then they are the transgressors -
