Mishkat al-Masabih #3355

Khishf b. Malik, on the authority of Ibn Mas'ud, said God’s Messenger gave judgment that the blood wit for accidental killing should be twenty female and twenty male camels which had entered their second year, twenty she-camels which had entered their third year, twenty she-camels in their fifth year and twenty she-camels in their fourth year. Tirmidhi, Abu Dawud and Nasa’i transmitted it, but the sound view is that it does not go back beyond Ibn Mas'ud. Khishf is unknown, being known only by this tradition. It is transmitted in Sharh as-sunna that the Prophet paid bloodwit for those slain at Khaibar from the camels of the sadaqa, but the male camel which has entered its second year is not among the age groups of the camels of the sadaqa, only the male camel which has entered its third year being included.
