Surah Al-Ahzaab, verse 55

لَّا جُنَاحَ عَلَيْهِنَّ فِىٓ ءَابَآئِهِنَّ وَلَآ أَبْنَآئِهِنَّ وَلَآ إِخْوَٰنِهِنَّ وَلَآ أَبْنَآءِ إِخْوَٰنِهِنَّ وَلَآ أَبْنَآءِ أَخَوَٰتِهِنَّ وَلَا نِسَآئِهِنَّ وَلَا مَا مَلَكَتْ أَيْمَٰنُهُنَّ ۗ وَٱتَّقِينَ ٱللَّهَ ۚ إِنَّ ٱللَّهَ كَانَ عَلَىٰ كُلِّ شَىْءٍۢ شَهِيدًا

There is no blame upon women concerning their fathers or their sons or their brothers or their brothers' sons or their sisters' sons or their women or those their right hands possess. And fear Allah. Indeed Allah is ever, over all things, Witness.
