It was narrated from 'Abdullah bin Masud that the Messenger of Allah (ﷺ) said:“The blood money of one who killed by mistake is twenty Hiqqah (three-year-old she camels), twenty Jadha'ah (four year old she camels), twenty Bint Makhad (one year old she camel), twenty Bint Labun (two year old she camels), and twenty Bani Makhad (one year old she camels).”
