Amr bin Shu'ayb (may Allah have mercy on him) said that a man of Banu Mudlij named Qatadah struck his son with a sword; it hit his shin, the wound was deep, and he died. Then Sayyiduna Suraqah bin Ju'shum (may Allah be pleased with him) came to Sayyiduna Umar (may Allah be pleased with him) and told him of this incident, and Sayyiduna Umar (may Allah be pleased with him) said: "Bring 120 camels for the diyah." He brought them. Sayyiduna Umar (may Allah be pleased with him) took from those camels 30 hiqqahs, 30 jadha'ahs and 40 that had young in their bellies, and asked: "Where is the brother of the slain man?" He said: Here I am. So he said: "Take the diyah. I heard the Prophet (peace and blessings be upon him) say: 'There is nothing for the killer.'"
