Sunan an-Nasa'i 4790

It was narrated that Ibn 'Abbad, who attributed it to the prophet, said:"Whoever is killed in the blind or by something thrown, with a rock, a whip, or a stick, then the blood money to be paid for him is the blood money for accidental killing. Whoever kills deliberately, then retaliation is upon him, and whoever tries to prevent that, upon him is the curse of Allah, the Angels and all the people, and Allah will not accept any Sarf nor 'Adl from him
