وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّ ابْنَ شِهَابٍ، وَسُلَيْمَانَ بْنَ يَسَارٍ، وَرَبِيعَةَ بْنَ أَبِي عَبْدِ الرَّحْمَنِ، كَانُوا يَقُولُونَ دِيَةُ الْخَطَإِ عِشْرُونَ بِنْتَ مَخَاضٍ وَعِشْرُونَ بِنْتَ لَبُونٍ وَعِشْرُونَ ابْنَ لَبُونٍ ذَكَرًا وَعِشْرُونَ حِقَّةً وَعِشْرُونَ جَذَعَةً ‏.‏ قَالَ مَالِكٌ الأَمْرُ الْمُجْتَمَعُ عَلَيْهِ عِنْدَنَا أَنَّهُ لاَ قَوَدَ بَيْنَ الصِّبْيَانِ وَإِنَّ عَمْدَهُمْ خَطَأٌ مَا لَمْ تَجِبْ عَلَيْهِمُ الْحُدُودُ وَيَبْلُغُوا الْحُلُمَ وَإِنَّ قَتْلَ الصَّبِيِّ لاَ يَكُونُ إِلاَّ خَطَأً وَذَلِكَ لَوْ أَنَّ صَبِيًّا وَكَبِيرًا قَتَلاَ رَجُلاً حُرًّا خَطَأً كَانَ عَلَى عَاقِلَةِ كُلِّ وَاحِدٍ مِنْهُمَا نِصْفُ الدِّيَةِ ‏.‏ قَالَ مَالِكٌ وَمَنْ قَتَلَ خَطَأً فَإِنَّمَا عَقْلُهُ مَالٌ لاَ قَوَدَ فِيهِ وَإِنَّمَا هُوَ كَغَيْرِهِ مِنْ مَالِهِ يُقْضَى بِهِ دَيْنُهُ وَيُجَوَّزُ فِيهِ وَصِيَّتُهُ فَإِنْ كَانَ لَهُ مَالٌ تَكُونُ الدِّيَةُ قَدْرَ ثُلُثِهِ ثُمَّ عُفِيَ عَنْ دِيَتِهِ فَذَلِكَ جَائِزٌ لَهُ وَإِنْ لَمْ يَكُنْ لَهُ مَالٌ غَيْرُ دِيَتِهِ جَازَ لَهُ مِنْ ذَلِكَ الثُّلُثُ إِذَا عُفِيَ عَنْهُ وَأَوْصَى بِهِ ‏.‏

Yahya related to me from Malikthat Ibn Shihab, Sulayman ibn Yasar, and Rabia ibn Abi Abd ar-Rahmansaid, "The blood-money of manslaughter is twenty yearlings, twentytwo-year-olds, twenty male two-year-olds, twenty four-year-olds, andtwenty five-year-olds." Malik said, "The generally agreed onway with us is that there is no retaliation against children. Theirintention is accidental. The hudud are not obliged for them if theyhave not yet reached puberty. If a child kills someone it is onlyaccidentally. Had a child and an adult killed a free man accidentally,each of them pays half the full blood-money." Malik said, "Aperson who kills someone accidentally pays blood-money with hisproperty and there is no retaliation against him. That money is likeanything else from the dead man's property and his debt is paid withit and he is allowed to make a bequest from it. If he has a totalproperty of which the blood-money is a third and then the blood-moneyis relinquished, that is permitted to him. If all the property he hasis his blood-money, he is permitted to relinquish a third of it and tomake that a bequest." Translation Not Available
