It is narrated from Sayyidah Zaynab bint Abi Salamah (may Allah be pleased with her) that she heard Sayyidah Umm Salamah (may Allah be pleased with her) and Sayyidah Umm Habibah (may Allah be pleased with her), both of them mentioning that a woman came to the Prophet (peace and blessings be upon him) and mentioned that her daughter's husband had died and her eyes had become diseased: may she apply kohl? The Messenger of Allah (peace and blessings be upon him) said: "One of you used to throw a piece of dung at the end of the year, and this is only four months and ten days."
Muslim narrated it.
