It is narrated from Hazrat Umm Salamah (may Allah be pleased with her) that a woman whose husband had passed away developed a complaint in her eyes. She mentioned this to the Prophet (peace and blessings be upon him) and sought permission to apply kohl to her eyes, saying, "We fear for her eyes." The Prophet (peace and blessings be upon him) said: (In the time of ignorance) one of you women would stay in her house for a whole year wearing the worst of clothes, then a dog would pass by her, and she would throw dung and come out. So can she not now spend four months and ten days?
