وَٱلْقَوَٰعِدُ مِنَ ٱلنِّسَآءِ ٱلَّٰتِى لَا يَرْجُونَ نِكَاحًا فَلَيْسَ عَلَيْهِنَّ جُنَاحٌ أَن يَضَعْنَ ثِيَابَهُنَّ غَيْرَ مُتَبَرِّجَٰتٍۭ بِزِينَةٍ ۖ وَأَن يَسْتَعْفِفْنَ خَيْرٌ لَّهُنَّ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ

And (as for) women advanced in years who do not hope for a marriage, it is no sin for them if they put off their clothes without displaying their ornaments; and if they restrain themselves it is better for them; and Allah is Hearing, Knowing.
