24:60
وَٱلْقَوَٰعِدُ مِنَ ٱلنِّسَآءِ ٱلَّـٰتِى لَا يَرْجُونَ نِكَاحًا فَلَيْسَ عَلَيْهِنَّ جُنَاحٌ أَن يَضَعْنَ ثِيَابَهُنَّ غَيْرَ مُتَبَرِّجَـٰتٍۭ بِزِينَةٍ ۖ وَأَن يَسْتَعْفِفْنَ خَيْرٌ لَّهُنَّ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ٦٠
And women of post-menstrual age who have no desire for marriage - there is no blame upon them for putting aside their outer garments [but] not displaying adornment. But to modestly refrain [from that] is better for them. And Allāh is Hearing and Knowing.
