Narrated Abdullah ibn Mas'ud:

The Prophet ﷺ said: The blood-wit for accidental killing should be twenty she-camels which had entered their fourth year, twenty she-camels which had entered their fifth year, twenty she-camels which had entered their second year, twenty she-camels which had entered their third year, and twenty male camels which had entered their second year. It does not beyond Ibn Mas'ud.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، حَدَّثَنَا الْحَجَّاجُ، عَنْ زَيْدِ بْنِ جُبَيْرٍ، عَنْ خِشْفِ بْنِ مَالِكٍ الطَّائِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" فِي دِيَةِ الْخَطَإِ عِشْرُونَ حِقَّةً وَعِشْرُونَ جَذَعَةً وَعِشْرُونَ بِنْتَ مَخَاضٍ وَعِشْرُونَ بِنْتَ لَبُونٍ وَعِشْرُونَ بَنِي مَخَاضٍ ذُكُرٌ " . وَهُوَ قَوْلُ عَبْدِ اللَّهِ .
