سنن أبي داود

Narrated 'Amr b. Suh'aib:

On his father's authority, said that his grandfather reported that the value of the blood-money at the time of the Messenger of Allah (ﷺ) was eight hundred dinars or eight thousand dirhams, and the blood-money for the people of the Book was half of that for Muslims.

He said: This applied till Umar (Allah be pleased with him) became caliph and he made a speech in which he said: Take note! Camels have become dear. So Umar fixed the value for those who possessed gold at one thousand dinars, for those who possessed silver at twelve thousand (dirhams), for those who possessed cattle at two hundred cows, for those who possessed sheep at two thousand sheep, and for those who possessed suits of clothing at two hundred suits. He left the blood-money for dhimmis (protected people) as it was, not raising it in proportion to the increase he made in the blood-wit.
