that the Messenger of Allah (ﷺ) said: "Whoever kills his slave, then we will kill him, and whoever maims his slave, then we will maim him."
Jami` at-Tirmidhi Book 16, Hadith 30
← Previous Hadith from his father, from his grandfather that the Messenger of Allah (ﷺ) said: "The Muslim is not killed for disbeliever."

And with this chain, it has been narrated that the Prophet (ﷺ) said: "The blood-money paid for disbeliever is half of the blood-money paid for a believer."

Jami` at-Tirmidhi Book 16, Hadith 29 Next Hadith → that 'Umar would say: "The blood-money upon the tribe, and the wife does not inherit any of her husband's blood-money." Until Ad-Dahhak bin Sufyan Al-Kulabi informed him that the Messenger of Allah (ﷺ) wrote to me, that Ashaim Ad-Dibabi's wife inherited the blood-money of her husband.
