457 — It is rigorously authenticated that the Messenger of Allah (peace and blessings be upon him) said: “It is not lawful for a woman who believes in Allah and the Last Day to mourn over a deceased person for more than three nights, except for her husband—for him she must mourn four months and ten days.” They unanimously agree on this ruling. Al-Hasan al-Basri alone differed, holding that mourning seclusion is not obligatory.

458 — They unanimously agree that a woman observing ihdād is forbidden to wear muʿaṣṣar—a saffron-dyed garment—apart from the concession already mentioned from al-Hasan. Wearing black, however, was deemed permissible by ʿUrwa ibn al-Zubayr, Mālik ibn Anas, and al-Shāfiʿī.

459 — They unanimously agree that a woman in mourning seclusion may not wear silk. ʿAṭāʾ alone held that it is not objectionable for her to keep wearing silver jewelry if she was already wearing it when her husband died.

460 — They unanimously agree that, during ihdād, a woman is barred from perfume and all other adornment, save for the allowance reported from al-Hasan.

461 — They unanimously agree that a woman whose husband still has the right to revoke the divorce may beautify herself and present herself attractively. Al-Shāfiʿī alone said: I prefer that she adorn herself but refrain from using perfume.
