24:60
وَٱلۡقَوَ ٰعِدُ مِنَ ٱلنِّسَاۤءِ ٱلَّـٰتِی لَا یَرۡجُونَ نِكَاحࣰا فَلَیۡسَ عَلَیۡهِنَّ جُنَاحٌ أَن یَضَعۡنَ ثِیَابَهُنَّ غَیۡرَ مُتَبَرِّجَـٰتِۭ بِزِینَةࣲۖ وَأَن یَسۡتَعۡفِفۡنَ خَیۡرࣱ لَّهُنَّۗ وَٱللَّهُ سَمِیعٌ عَلِیمࣱ
As for women past child-bearing, who have no hope of marriage, it is no sin for them if they discard their (outer) clothing in such a way as not to show adornment. But to refrain is better for them. Allah is Hearer, Knower.
