Narrated Humaid bin Nafi:
Zainab bint Abu Salama told me these three narrations: Zainab said: I went to Um Habiba, the wife of the Prophet ﷺ when her father, Abu- Sufyan bin Herb had died. Um ,Habiba asked for a perfume which contained yellow scent (Khaluq) or some other scent, and she first perfumed one of the girls with it and then rubbed her cheeks with it and said, "By Allah, I am not in need of perfume, but I have heard Allahs Apostle ﷺ saying, It is not lawful for a lady who believes in Allah and the Last Day to mourn for a dead person for more than three days unless he is her husband for whom she should mourn for four months and ten days. " Zainab further said: I want to Zainab bint Jahsh when her brother died. She asked for perfume and used some of it and said, "By Allah, I am not in need of perfume, but I have heard Allahs Apostle ﷺ saying on the pulpit, It is not lawful for a lady 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. " Zainab further said, "I heard my mother, Um Salama saying that a woman came to Allahs Apostle ﷺ and said, "O Allahs Apostle ﷺ ! The husband of my daughter has died and she is suffering from an eye disease, can she apply kohl to her eye?" Allahs Apostle ﷺ replied, "No," twice or thrice. (Every time she repeated her question) he said, "No." Then Allahs Apostle ﷺ added, "It is just a matter of four months and ten days. In the Pre-Islamic Period of ignorance a widow among you should throw a globe of dung when one year has elapsed." I said to Zainab, "What does throwing a globe of dung when one year had elapsed mean?" Zainab said, "When a lady was bereaved of her husband, she would live in a wretched small room and put on the worst clothes she had and would not touch any scent till one year had elapsed. Then she would bring an animal, e.g. a donkey, a sheep or a bird and rub her body against it. The animal against which she would rub her body would scarcely survive. Only then she would come out of her room, whereupon she would be given a globe of dung which she would throw away and then she would use the scent she liked or the like."
