On the authority of Umm ʿAṭiyyah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "No woman should observe mourning for a deceased person for more than three days, except a woman who observes mourning for her husband for four months and ten days. She should not wear a dyed garment except a garment of ʿaṣb, and she should not apply kohl, and she should not perfume herself except at the onset of her purity, with a small amount of qusṭ and ẓufār."

36 - Chapter: A man whose father commands him to divorce his wife

2088 - Muḥammad ibn Bashshār narrated to us, Yaḥyā ibn Saʿīd al-Qaṭṭān and ʿUthmān ibn ʿUmar narrated to us, they said: Ibn Abī Dhiʾb narrated to us, from his maternal uncle al-Ḥārith ibn ʿAbd al-Raḥmān, from Ḥamzah ibn ʿAbd Allah ibn ʿUmar--------------------------------------------
(1) Its chain of transmission is authentic. Ḥafṣah: she is the daughter of Sīrīn, the sister of Muḥammad.
It was also recorded by al-Bukhārī (313) and (5343), and Muslim following (1491): (66) and (67), and Abū Dāwūd (2302) and (2303), and al-Nasāʾī 6/202-203 and 206, from the route of Ḥafṣah, with this chain of transmission.
It is in the "Musnad of Aḥmad" (25794), and "Ṣaḥīḥ Ibn Ḥibbān" (4305).
His saying: "a garment of ʿaṣb" — al-Sindī said: with a fatḥah then a sukūn: it is Yemeni cloth whose thread is bound, i.e., tied, then dyed and woven, so what was bound remains white, untouched by the dye. And it was said: striped cloth. It was said: on the first interpretation, the prohibition for the mourning woman concerns what was dyed after weaving. I say (the speaker is al-Sindī): the closest is that the prohibition concerns what was entirely dyed, for the attribution to ʿaṣb necessitates that, since its making prevented the whole from being dyed, so reflect.
"At the onset of her purity": the beginning of her purity.
"A small amount" (nubdhah): it is a little of something.
"Qusṭ": al-Nawawī said: qusṭ and ẓufār are well-known types of incense; permission was granted for them to remove an unpleasant odor, not for perfuming, and Allah knows best.
