Hadith.5220 - Muhammad ibn Aslam narrated from Ali ibn Abi Hamzah from Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim (as), who said: I asked Imam (as): "May I be your ransom! A man was killed, whether intentionally or accidentally, and he had debts and wealth. His heirs wanted to pardon the killer. What is the ruling?" Imam (as) said: "If they pardon his blood, they are responsible for paying his debts." I asked: "What if they wish to execute the killer?" Imam (as) said: "If he is killed intentionally, his killer is to be executed, and the Imam will pay his debt from the gharimin (debtors) portion of the public treasury (Bayt Al-Mal)." I asked: "If he was killed intentionally and his heirs reconciled with the killer for blood money (diyyah), who is responsible for the debt? Is it upon his heirs from the blood money or upon the Imam of the Muslims?" Imam (as) replied: "Rather, they must pay his debt from the diyyah they accepted in the settlement because he is more entitled to his blood money than anyone else."

Hadith.5222 - Al-Bazanti narrated from Abdullah ibn Sinan from Abu Abdullah (as) regarding a man who struck another man on the head with a stick, causing his speech to become impaired. Imam (as) said: "He should be tested with the letters of the Arabic alphabet. For the letters he can articulate clearly, there is no liability. But for the letters he cannot pronounce clearly, there is blood money (diyyah) due for each, and the total is twenty-eight letters."
