Narrated Zainab bint Abi Salama: I went to Um Habiba, the wife of Prophet, who said, "I heard the Prophets saying, 'It is not legal for a woman who believes in Allah and the Last Day to mourn for any dead person for more than three days except for her husband, (for whom she should mourn) for four months and ten days'."
