It is narrated from Sayyidah Umm Atiyyah (may Allah be pleased with her): "We were forbidden to mourn for a deceased person for more than three days, except for a husband, (for whom we mourned) four months and ten days; and (we were told) not to apply kohl, nor apply perfume, nor wear dyed clothes except a garment of 'asb. But it was permitted at her purification, when one of us took the bath after her menstruation, (to use) a little qust or azfar (types of fragrant incense)."
Muslim narrated it.
