عَنْ زَيْنَبَ بِنْتِ أُمِّ سَلَمَةَ عَنْ أُمِّهَا إِنَّ امْرَأَةً تُوُفِّيَ زَوْجُهَا فَاشْتَكَتْ عَيْنُهَا، فَذَكَرُوهَا لِلنَّبِيِّ صلى الله عليه وآله وسلم وَذَكَرُوا الْكُحْلَ، قَالُوا: نَخَافُ عَلَى عَيْنِهَا، قَالَ صلى الله عليه وآله وسلم: ((قَدْ كَانَتْ إِحْدَاكُنَّ تَمْكُثُ فِي بَيْتِهَا فِي شَرِّ أَحْلَاسِهَا فِي شَرِّ بَيْتِهَا حَوْلًا فَإِذَا مَرَّ بِهَا كَلْبٌ رَمَتْ بِبَعْرَةٍ أَفَلَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا۔))
Lady Umm Salamah (may Allah be pleased with her) narrates that a woman's husband died and her eye became diseased. Her family mentioned this matter to the Noble Prophet (peace and blessings be upon him) and sought permission to apply kohl. They said, "We fear that her eye may be harmed." The Prophet (peace and blessings be upon him) said: "One of you women used to stay in her house in the worst clothes, in the worst place, for a whole year, and when a dog would pass by her, she would throw dung at it. Can she not now be patient for four months and ten days?"
