Sayyidah Umm ‘Atiyyah Ansariyyah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) said: No woman should observe mourning for any deceased person for more than three days, except for her husband, for whom she will observe mourning for four months and ten days. During this period, she should not wear dyed clothes, but she may wear clothes made of dyed yarn. She should not apply kohl, nor use perfume, except that when she becomes pure after menstruation, she may use a little qust or azfar perfume.
