Emphasis on hijab for women and an exemption
The injunction on hijab for women has already appeared earlier in detail in two verses, and two exemptions were also mentioned there. One exemption relates to the one who is seeing, and the other to that who is seen. According to the first exemption, young children and the slave girls are exempt. As for the second exemption, the outward adornment is exempt from hijab, which includes outer clothing like veil or covering sheet. There is agreement of all on this, but according to some, women's face and palms are also included in this exemption.
In the next verse the third exemption is granted on the basis of a woman's personal situation. If a woman has grown so old that no one would have any (sexual) desire towards her, nor is she marriageable, for such a woman concession in hijab is allowed in that even strangers (non-Mahrams) are treated like mahrams for her. She is not required to cover those parts of her body before non-Mahrams which are not required to be covered before mahrams. Hence, it is said وَالْقَوَاعِدُ مِنَ النِّسَاءِ اللَّاتِي (And those old women who have no hope for marriage - 60). The explanation of this verse is already given above. Although very old women are allowed to uncover those parts of their body before non-Mahrams which are not required to be covered before mahrams, yet this exemption is allowed with the condition that they do so without applying any makeup or adornment. The other thing said in the last is وَأَن يَسْتَعْفِفْنَ خَيْرٌ لَّهُنَّ (60) that is, it is better for them if they avoid going before non-Mahrams altogether.
