I asked Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as), "May Allah rectify your affairs. Some people have thirty-two teeth in their mouths, while others have twenty-eight. Upon how many teeth is the diyyah (blood money) calculated?" Imam (as) said: "The natural creation consists of twenty-eight teeth - twelve in the front of the mouth and sixteen in the back. The diyyah of the teeth has been distributed based on this. The diyyah for each of the twelve front teeth, if broken and completely lost, is five hundred dirhams, making the total diyyah for them six thousand dirhams. The diyyah for each of the sixteen molars, if broken and completely lost, is two hundred and fifty dirhams, making the total diyyah for them four thousand dirhams. Thus, the total diyyah for both the front and back teeth amounts to ten thousand dirhams. The diyyah has been set according to this calculation, so any extra teeth beyond twenty-eight have no diyyah, nor is there a diyyah for any missing teeth beyond this standard count." And thus, we found it recorded in the book of Commander of the Faithful Imam Ali ibn Abi Talib (as). Al-Hakam said: I then asked, "Before today, diyyah (blood money) used to be taken from camels, cows, and sheep. What is the ruling on that?" Imam (as) said: "That was in the desert communities before Islam. But when Islam became widespread and silver (warq) became abundant among people, Commander of the Faithful Imam Ali ibn Abi Talib (as), set the diyyah in terms of silver." Al-Hakam continued: I then asked Imam (as), "What about those who live in the desert today? What should be taken from them as diyyah - silver or camels?" Imam (as) said: "Camels are equivalent to silver, rather, they are even better than silver for diyyah. Indeed, they used to take one hundred camels for unintentional killing (diyat Al-khata'), with each camel being valued at one hundred dirhams, making a total of ten thousand dirhams." I asked: "What are the required ages of the one hundred camels?" Imam (as) said: "They should all be male camels that have completed one full year."
