Can a mourning lady use kohl?

Narrated Um Salama:

A woman was bereaved of her husband and her relatives worried about her eyes (which were diseased). They came to Allah's Messenger (ﷺ) , and asked him to allow them to treat her eyes with kohl, but he said, "She should not apply kohl to her eyes. (In the Pre-Islamic period of Ignorance) a widowed woman among you would stay in the worst of her clothes (or the worst part of her house) and when a year had elapsed, if a dog passed by her, she would throw a globe of dung, Nay, (she cannot use kohl) till four months and ten days have elapsed."

حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا حُمَيْدُ بْنُ نَافِعٍ، عَنْ زَيْنَبَ ابْنَةِ أُمِّ سَلَمَةَ، عَنْ أُمِّهَا، أَنَّ امْرَأَةً، تُوُفِّيَ زَوْجُهَا فَخَشُوا عَلَى عَيْنَيْهَا فَأَتَوْا رَسُولَ اللَّهِ صلى الله عليه وسلم فَاسْتَأْذَنُوهُ فِي الْكُحْلِ فَقَالَ ‏

‏ لاَ تَكَحَّلْ قَدْ كَانَتْ إِحْدَاكُنَّ تَمْكُثُ فِي شَرِّ أَحْلاَسِهَا أَوْ شَرِّ بَيْتِهَا، فَإِذَا كَانَ حَوْلٌ فَمَرَّ كَلْبٌ رَمَتْ بِبَعَرَةٍ، فَلاَ حَتَّى تَمْضِيَ أَرْبَعَةُ أَشْهُرٍ وَعَشْرٌ ‏

‏‏.‏

Narrated Um Habiba:

The Prophet (ﷺ) said, "It is not lawful for a Muslim woman who believes in Allah and the Last Day to mourn for more than three days, except for her husband, for whom she should mourn for four months and ten days."

وَسَمِعْتُ زَيْنَبَ ابْنَةَ أُمِّ سَلَمَةَ، تُحَدِّثُ عَنْ أُمِّ حَبِيبَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏

‏ لاَ يَحِلُّ لاِمْرَأَةٍ مُسْلِمَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ أَنْ تُحِدَّ فَوْقَ ثَلاَثَةِ أَيَّامٍ، إِلاَّ عَلَى زَوْجِهَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا ‏

‏‏.‏

Narrated Um 'Atiyya:

We were forbidden to mourn for more than three days except for a husband.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرٌ، حَدَّثَنَا سَلَمَةُ بْنُ عَلْقَمَةَ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، قَالَتْ أُمُّ عَطِيَّةَ نُهِينَا أَنْ نُحِدَّ أَكْثَرَ مِنْ ثَلاَثٍ إِلاَّ بِزَوْجٍ‏.‏
