It is narrated from Hazrat Umm Atiyyah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: It is not permissible to mourn for any deceased person for more than three days. However, a woman will mourn for her husband for four months and ten days. She will not wear dyed clothes; she may only wear clothes made of rough cloth. She will not apply kohl or use perfume, except that when she becomes pure (after menstruation), she may use a little bit of incense or aloeswood.
