Quran 24:60 from Surah An-Noor on Divine Marvels.
وَٱلۡقَوَٰعِدُ مِنَ ٱلنِّسَآءِ ٱلَّٰتِي لَا يَرۡجُونَ نِكَاحٗا فَلَيۡسَ عَلَيۡهِنَّ جُنَاحٌ أَن يَضَعۡنَ ثِيَابَهُنَّ غَيۡرَ مُتَبَرِّجَٰتِۭ بِزِينَةٖۖ وَأَن يَسۡتَعۡفِفۡنَ خَيۡرٞ لَّهُنَّۗ وَٱللَّهُ سَمِيعٌ عَلِيمٞ
English translation: And postmenopausal among the women who (do) not have desire (for) marriage then not is on them any blame that they put aside their (outer) garments not displaying their adornment And that they modestly refrain (is) better for them And Allah (is) All-Hearer All-Knower
Transliteration: wal-qawa'idu mina al-nisai allati la yarjuna nikahan falaysa alayhinna junahun an yada'na thiyabahunna ghayra mutabarrijatin bizinatin wa-an yasta'fif'na khayrun lahunna wal-lahu sami'un alimun
