﴿ وَٱلْقَوَٰعِدُ مِنَ ٱلنِّسَآءِ ٱلَّٰتِى لَا يَرْجُونَ نِكَاحًۭا فَلَيْسَ عَلَيْهِنَّ جُنَاحٌ أَن يَضَعْنَ ثِيَابَهُنَّ غَيْرَ مُتَبَرِّجَٰتٍۭ بِزِينَةٍۢ ۖ وَأَن يَسْتَعْفِفْنَ خَيْرٌۭ لَّهُنَّ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌۭ ﴾

“AND [know that] women advanced in years, who no longer feel any sexual desire, incur no sin if they discard their [outer] garments, provided they do not aim at a showy display of [their] charms. But [even so,] it is better for them to abstain [from this]: and God is all-hearing, all-knowing.”

(As for women past child-bearing, who have no hope of marriage) and do not need to get married, (it is no sin for them) for such women (if they discard their (outer) clothing) in front of strange people (in such a way as not to show adornment) without adorning themselves or showing their adornment to strangers. (But to refrain) to keep their outer garment on (is better for them) than discarding it. (Allah is Hearer) He hears what they say, (Knower) He knows their deeds.
