Sayyida Umm Atiyyah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) said: It is not permissible for a woman who believes in Allah and the Last Day to mourn for any deceased person for more than three days, except for her husband, for whom she will mourn for four months and ten days. She should not apply kohl, nor wear colored clothing, except for a garment made of dyed yarn (which was dyed before being woven). She should not apply perfume, except when she becomes pure after menstruation (then she may apply a little perfume).
