سنن أبي داود

Narrated Abdullah ibn Mas'ud:

The Prophet (ﷺ) said: The blood-wit for accidental killing should be twenty she-camels which had entered their fourth year, twenty she-camels which had entered their fifth year, twenty she-camels which had entered their second year, twenty she-camels which had entered their third year, and twenty male camels which had entered their second year. It does not beyond Ibn Mas'ud.
