"Every Muslim and Muslimah should receive the death (of a relative or an associate) patiently showing their acceptance of Allah's verdict. The maximum period of mourning for a woman is four months and ten days, if the deceased is her husband, and three days for relatives and other persons. It is impermissible for a woman to exceed these periods for the Prophet, peace and blessings be upon him, said: "It is not legal for a woman who believes in Allah and the Last Day to mourn for more than three days for any dead person except her husband, for whom she should mourn for four months and ten days."

What about mother, sister, daughter etc? They cant mourn for their lost ones for more than 3 days?
