Hadith.5281 - Ibn Mahbub narrated from Abu Ayyub from Buraid Al-Ijli from Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) who said: "For the tongue of a mute person, the eye of a blind person, and the private parts and testicles of a free eunuch, one-third of the full blood money (diyya) is due. However, for the private part of a young boy, the full blood money is due."

Hadith.5283 - Ibn Mahbub narrated from Jamil ibn Salih from Abu Ubaydah Al-Hadhdha' who said: I asked Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) about a man who struck another man on his head with the pole of a tent, delivering a single blow that penetrated to his brain, causing him to lose his mind. Imam (as) said: "If the struck man can no longer comprehend the prayer, nor understand what is said to him or what he says, then he should be observed for a year. If he dies within that year, the striker is subject to retaliation (qisas). However, if he does not die within that period and his mind does not return, the striker must pay the full blood money (diyya) from his wealth due to the loss of the victim's intellect." I said to Imam (as): What do you rule upon him regarding the head injury (shajja)? Imam (as) replied: "Nothing, because he only struck him once, and that single blow caused two injuries. Therefore, I imposed upon him the more severe of the two injuries, which is the blood money (diyya). Had he struck him twice, causing two separate injuries, I would have imposed upon him compensation for both injuries, whatever they may have been - except if one of them resulted in death, in which case the striker would face retaliation (qisas), and the second injury would be disregarded." Imam (as) further said: "If he struck him three times, one after the other, resulting in three injuries, I would impose upon him the liability for whatever the three injuries amounted to, unless one of them led to death, in which case the striker would face retaliation." Imam (as) added: "And if he struck him ten times, but they resulted in a single injury, I would hold him accountable only for that single injury caused by the ten blows, regardless of its severity, as long as it did not result in death."
