Musnad Ahmad 28:555

Ya'qub narrated to us, my father narrated to us, from Muhammad ibn Ishaq, and he mentioned a hadith. Ibn Ishaq said: And 'Amr ibn Shu'ayb ibn Muhammad ibn 'Abdullah ibn 'Amr ibn al-'As mentioned, from his father, from his grandfather, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever kills a believer intentionally, he is handed over to the guardians of the slain. If they wish, they may kill [him], and if they wish, they may take the blood money (diyah). It is thirty hiqqah (four-year-old camels), thirty jadha'ah (five-year-old camels), and forty khilfah (pregnant camels). That is the blood money for intentional killing. Whatever they agree upon as a settlement is theirs, and that is the severe blood money. The blood money for quasi-intentional killing is aggravated, like the blood money for intentional killing, but its perpetrator is not killed. That is when Satan incites [strife] between people, resulting in bloodshed without malice or the carrying of weapons." For the Messenger of Allah (peace and blessings of Allah be upon him) said—meaning: "Whoever carries weapons against us is not one of us," nor [is it] lying in wait on a road. Whoever is killed other than that, it is quasi-intentional; its blood money is aggravated, its perpetrator is not killed, and it is [also] in the Sacred Month, for the sanctity [of the place], and for the neighbor. Whoever kills by mistake, his blood money is one hundred camels: thirty bint makhad (one-year-old female camels), thirty bint labun (two-year-old female camels), thirty hiqqah (four-year-old camels), and ten male ibn labun (two-year-old male camels). He said: The Messenger of Allah (peace and blessings of Allah be upon him) used to value it for the people of the villages at four hundred dinars, or its equivalent in silver (wariq). He used to value it based on the prices of camels; if they became expensive, he increased its value, and if they became cheap, he decreased its value, according to the state of the times. In the time of the Messenger of Allah (peace and blessings of Allah be upon him), it reached between four hundred dinars and eight hundred dinars, and its equivalent in silver was eight thousand dirhams. He decreed that whoever’s blood money was upon the people of cattle, it was two hundred cows. He decreed that whoever’s blood money was upon the people of sheep, it was two thousand sheep. He decreed regarding the nose, if it is completely cut off, the full blood money is due. If its tip is cut off, half the blood money is due. He decreed regarding the eye, half the blood money—fifty camels, or its equivalent in gold or silver, or one hundred cows, or one thousand sheep. The leg is half the blood money, and the hand is half the blood money. The ma'mumah (head wound reaching the brain) is one-third of the blood money—thirty-three camels, or its value in gold, silver, cows, or sheep. The ja'ifah (abdominal wound) is one-third of the blood money. The munqilah (bone-displacing wound) is fifteen camels. The mudihah (bone-exposing wound) is five camels, and the teeth are five camels.
