Abu Dawud and At-Tirmidhi transmitted on the authority of 'Amro bin Shu'aib on his father’s authority, who reported from his grandfather (RAA), who reported that the Messenger of Allah (ﷺ) said: “The Diyah (of intentional homicide) is paid in three different types of camels: 30 she-camels ‘hiqqah’ (in their fourth year), 30 she-camels ‘Jaz'ah’ (in their fifth year), and 40 pregnant she-camels.”
