Abu Dawud Book 34, Hadith Number 4502.
Chapter : If a man kills his slave or cuts off one of his limbs retaliation will be taken on him.
Narated By N/A : Qatadah said through the same chain of narrators as mentioned before, i.e. Samurah reported the Apostle of Allah (may peace be upon him) as saying.: If one castrates his slave, we shall castrate him. He then mentioned the rest of the addition like that of Shu’bah and Hammad.
Abu Dawud said: Abu Dawud al-Tayalisi transmited it from Hisham like the condition of Mu’adh.
