Surah Al-Ahzab, verse 55

لَّا جُنَاحَ عَلَيْهِنَّ فِىٓ ءَابَآئِهِنَّ وَلَآ أَبْنَآئِهِنَّ وَلَآ إِخْوَٰنِهِنَّ وَلَآ أَبْنَآءِ إِخْوَٰنِهِنَّ وَلَآ أَبْنَآءِ أَخَوَٰتِهِنَّ وَلَا نِسَآئِهِنَّ وَلَا مَا مَلَكَتْ أَيْمَـٰنُهُنَّ ۗ وَٱتَّقِينَ ٱللَّهَ ۚ إِنَّ ٱللَّهَ كَانَ عَلَىٰ كُلِّ شَىْءٍ شَهِيدًا ﴿٥٥﴾
