It is narrated from Hazrat Umm Atiyyah (may Allah be pleased with her) that the Prophet (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 should mourn for four months and ten days. She should not wear clothes dyed with any color except 'asab, nor apply kohl, nor use perfume, except when she becomes pure after her menstrual period, then she may use a little qust or azfar perfume.
