Surah 24. An-Nur
Ayah 60
60وَٱلْقَوَٰعِدُ مِنَ ٱلنِّسَآءِ ٱلَّـٰتِى لَا يَرْجُونَ نِكَاحًا فَلَيْسَ عَلَيْهِنَّ جُنَاحٌ أَن يَضَعْنَ ثِيَابَهُنَّ غَيْرَ مُتَبَرِّجَـٰتٍۭ بِزِينَةٍ ۖ وَأَن يَسْتَعْفِفْنَ خَيْرٌ لَّهُنَّ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ
[60] There is no sin for such elderly women as are past the age of marriage,92 if they lay aside their outer garments93 provided that they do not mean to display their adornment.94 Nevertheless, if they behave modestly, it would be better for them: for Allah hears everything and knows everything.
92Literally, "the seated women". This means those women who are no longer capable of bearing children, who no longer cherish sexual desires, and who cannot excite the passions of men.
93Literally, "if they lay aside their clothes". Obviously it cannot mean that they should strip themselves naked. That is why all the jurists and commentators . are agreed that it implies the outer garments which are used to hide the adornments as enjoined in Al-Ahzab: 59.
94"Tabarruj " is display and exhibitionism. When used with regard to a woman, it would imply the one who displays her charms and adornments before other men. The permission to lay aside the outer garments is being given to those old women who are no longer interested in personal embellishments and whose sex desires are gone. But if they still have a hidden desire smoldering in their hearts and an urge to display, they cannot avail of this permission.
