It was narrated from Sa'eed bin Musayyab that 'Umar used to say:
“The blood money is for the near male relatives from the father's side and the wife does not inherit anything from the blood money of her husband,” until Ad-Dahhak bin Sufyan wrote to him, and told him that the Prophet ﷺ ruled that the wife of Ashyam bin Dibabi should inherit from the blood money of her husband.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ عُمَرَ، كَانَ يَقُولُ الدِّيَةُ لِلْعَاقِلَةِ وَلاَ تَرِثُ الْمَرْأَةُ مِنْ دِيَةِ زَوْجِهَا شَيْئًا حَتَّى كَتَبَ إِلَيْهِ الضَّحَّاكُ بْنُ سُفْيَانَ أَنَّ النَّبِيَّ ﷺ وَرَّثَ امْرَأَةَ أَشْيَمَ الضِّبَابِيِّ مِنْ دِيَةِ زَوْجِهَا .
