Humaid b. Nafi' narrated two traditions from Umm Salama dealing with collyrium and the other hadith from the wives of Allah's Prophet (ﷺ) except with this that no mention was made of Zainab.
Sahih Muslim Book 18, Hadith 77
← Previous Hadith One among you used to spend one year in a dungeon dressed in worst clothes. (And at the end of this period) she threw dung at the dog which happened to pass that way and then she came out (of her 'Idda). Can't she (wait) even for four months and ten days?

Sahih Muslim Book 18, Hadith 76 Next Hadith → Umm Salama and Umm Habiba (Allah be pleased with them) were talking with each other (and saying) that a woman came to Allah's Messenger (ﷺ) and mentioned to him that her daughter had lost her husband, and her eyes were sore and she wanted to use collyrium, whereupon Allah's Messenger (ﷺ) said: One among you used to throw dung at the end of a year, and now (this abstinence from adornment) is only for four months and ten days.
