وَ رَوَى إِسْمَاعِيلُ بْنُ أَبِي زِيَادٍ عَنْ أَبِي عَبْدِ اللَّهِ ع أَنَّ مُحَمَّدَ بْنَ أَبِي بَكْرٍ رَضِيَ اللَّهُ عَنْهُ كَتَبَ إِلَى أَمِيرِ الْمُؤْمِنِينَ ع يَسْأَلُهُ عَنْ رَجُلٍ مَجْنُونٍ قَتَلَ رَجُلًا عَمْداً فَجَعَلَ ع الدِّيَةَ عَلَى قَوْمِهِ وَ جَعَلَ خَطَأَهُ وَ عَمْدَهُ سَوَاءً.

Hadith.5228 - Ismaʿil ibn Abi Ziyad narrated from Abu Abdullah (as) that Muhammad ibn Abi Bakr (may Allah (swt) be pleased with him) wrote to the Commander of the Faithful (as) asking about a mentally ill man who intentionally killed another man. The Commander of the Faithful (as) ruled that the blood money (diyyah) was upon his tribe (Aqilah) and that both his accidental and intentional acts were to be treated the same.
