وَٱلْقَوَٰعِدُ مِنَ ٱلنِّسَآءِ ٱلَّٰتِى لَا يَرْجُونَ نِكَاحًۭا فَلَيْسَ عَلَيْهِنَّ جُنَاحٌ أَن يَضَعْنَ ثِيَابَهُنَّ غَيْرَ مُتَبَرِّجَٰتٍۭ بِزِينَةٍۢ ۖ وَأَن يَسْتَعْفِفْنَ خَيْرٌۭ لَّهُنَّ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌۭ
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.
Surah An-Noor(24:60)
Sahih al-Bukhari
Supporting the Family
Chapter: The superiority of providing for one's family
Narrated Sa`d:
The Prophet (ﷺ) visited me at Mecca while I was ill. I said (to him), "I have property; May I bequeath all my property in Allah's Cause?" He said, "No." I said, "Half of it?" He said, "No." I said, "One third of it?" He said, "One-third (is alright), yet it is still too much, for you'd better leave your inheritors wealthy than leave them poor, begging of others. Whatever you spend will be considered a Sadaqa for you, even the mouthful of food you put in the mouth of your wife. Anyhow Allah may let you recover, so that some people may benefit by you and others be harmed by you."
