Bulugh al-Maram: Hadith 450

"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 lAbu n' (in their third year) and 20 he-camels 'ibn lAbu n' (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 lAbu n."
