Yahya related to me from Malik from Ibn Shihab that Umar ibn al- Khattab demanded of the people at Mina, "If anyone has knowledge of blood-money, let him inform me." Ad-Dahhak ibn Sufyan al-Kilabi stood up and said, "The Messenger of Allah ﷺ wrote to me that the wife of Ashyam ad-Dibabi inherited from 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 came in, ad-Dahhak told him about it and Umar ibn al-Khattab gave a decision based on that.
Ibn Shihab said, "The killing of Ashyam was accidental."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، نَشَدَ النَّاسَ بِمِنًى مَنْ كَانَ عِنْدَهُ عِلْمٌ مِنَ الدِّيَةِ أَنْ يُخْبِرَنِي . فَقَامَ الضَّحَّاكُ بْنُ سُفْيَانَ الْكِلاَبِيُّ فَقَالَ كَتَبَ إِلَىَّ رَسُولُ اللَّهِ ﷺ أَنْ أُوَرِّثَ امْرَأَةَ أَشْيَمَ الضِّبَابِيِّ مِنْ دِيَةِ زَوْجِهَا . فَقَالَ لَهُ عُمَرُ بْنُ الْخَطَّابِ ادْخُلِ الْخِبَاءَ حَتَّى آتِيَكَ فَلَمَّا نَزَلَ عُمَرُ بْنُ الْخَطَّابِ أَخْبَرَهُ الضَّحَّاكُ فَقَضَى بِذَلِكَ عُمَرُ بْنُ الْخَطَّابِ . قَالَ ابْنُ شِهَابٍ وَكَانَ قَتْلُ أَشْيَمَ خَطَأً .
