Chapter on the Blood Money for the Tongue of a Mute Person

Al-Hasan ibn Mahbub narrated from Hisham ibn Salim from Abu Baṣir from Abu Jafar Imam Muhammad ibn Ali Al-Baqir عليه السلام that someone from the family of Zurarah asked Imam عليه السلام about a man who cut off the tongue of a mute person. Imam عليه السلام said: "If his mother gave birth to him mute, then the full blood money (diyyah) is due. But if his tongue was lost due to an illness or an affliction after he had been able to speak, then the one who cut it off must pay one-third of the diyyah of the tongue."
