Ibn Mas'ud (RAA) narrated that The Messenger of Allah (ﷺ) said:
"The Diyah for accidental killing is paid in five types of camel indemnity: 20 she-camels 'hiqqah' (in their fourth year), 20 she-camels 'Jaz'ah' (in their fifth year), 20 she-camels 'bint makhad' (in their second year), 20 she-camels 'bint labun' (in their third year) and 20 he-camels 'ibn labun' (in their third year)."Related by Ad-Daraqutni with a strong chain of narrators. The four Imams reported it with this version, "twenty 'ibn makhad' (twenty male camels which had entered their second year)," instead of "ibn labun."
