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
There is no sin on them [in socializing freely] with their fathers, or their sons, or their brothers, or their brothers’ sons, or the sons of their sisters, or their own womenfolk, or what their right hands own. Be wary of Allah. Indeed Allah is witness to all things.
