Muwatta Malik 1579
موطأ مالك#1579SahihThese are the words of a Successor — the generation after the Companions — not of the Prophet ﷺ.

Yahya related to me from Malik that he heard that Umar ibn Abd al-Aziz gave a decision that when a jew or christian was killed, his blood-money was half the blood-money of a free muslim. Malik said, "What is done in our community, is that a muslim is not killed for a kafir unless the muslim kills him by deceit. Then he is killed for it
