It is narrated from Sa'id bin al-Musayyib (may Allah have mercy on him) that 'Umar bin al-Khattab (may Allah be pleased with him) used to say that blood money is obligatory upon the heirs, and a wife will not inherit anything from her husband's blood money. Until Dahhak bin Sufyan (may Allah be pleased with him) informed him that the Messenger of Allah (ﷺ) had written to him instructing that the wife of Ashyam al-Dhibabi (may Allah be pleased with him) should be made an heir to his blood money. Then 'Umar (may Allah be pleased with him) retracted his previous position.
