A relative of Umm Habībah died, so she asked for a yellow perfume and wiped it over her arms and said: "I do this only because I heard the Messenger of Allah (may Allah’s peace and blessings be upon him) say: It is not lawful for a woman who believes in Allah and the Last Day to mourn for a deceased more than three [days], but for her husband, four months and ten days.'"
