AN NUUR — Ayat 60

وَالْقَوَاعِدُ مِنَ النِّسَاء اللَّاتِي لَا يَرْجُونَ نِكَاحًا فَلَيْسَ عَلَيْهِنَّ جُنَاحٌ أَن يَضَعْنَ ثِيَابَهُنَّ غَيْرَ مُتَبَرِّجَاتٍ بِزِينَةٍ وَأَن يَسْتَعْفِفْنَ خَيْرٌ لَّهُنَّ وَاللَّهُ سَمِيعٌ عَلِيمٌ

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 Allah is Hearing and Knowing.
