Yahya related to me from Malik from Ibn Shihab that Umar ibn al-Khattab demanded of the people at Mina, "If anyone has knowledge ofblood-money, let him inform me." Ad-Dahhak ibn Sufyan al-Kilabi stoodup and said, "The Messenger of Allah, may Allah bless him and granthim peace, wrote to me that the wife of Ashyam ad-Dibabi inheritedfrom the blood-money of her husband." Umar ibn al-Khattab said to him,"Go into the tent until I come to you." When Umar ibn al-Khattab camein, ad-Dahhak told him about it and Umar ibn al-Khattab gave adecision based on that.Ibn Shihab said, "The killing ofAshyam was accidental."
