Hadith.3252 - Abu Jafar Imam Muhammad ibn Ali Al-Baqir عليه السلام said: During the time of Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام, a man was found slaughtered in a deserted place. Nearby, there was another man holding a knife covered in blood. He was arrested and brought before Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام. The man confessed, saying that he had killed the victim. However, another man approached and said to them, "Release him, for I am the one who killed your companion." He too was arrested and brought along with the first man before Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام. When they presented their case, Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام asked the first man: "What made you confess?" He replied: "O Commander of the Faithful, I am a butcher. I had slaughtered a sheep near the deserted place, and I urgently needed to relieve myself. So, I entered the deserted place with a knife in my hand, stained with blood. These people saw me, accused me of killing their companion, and arrested me. I thought that denying it would be of no use, since there was a man slaughtered and I was holding a bloodied knife, so I confessed." Then Commander of the Faithful Imam Ali عليه السلام asked the second man: "What do you say?" He replied: "I am the one who killed him, O Commander of the Faithful." Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام said: "Take them to my son, Imam Hasan ibn Ali عليه السلام, so he may judge between you." They went to Imam Hasan ibn Ali عليه السلام and presented the case. Imam Hasan ibn Ali عليه السلام said: "As for this one, if he has killed a man, he has also given life to this one (the butcher). And Allah سبحانه وتعالى, the Mighty and Majestic, says: 'And whoever saves a life, it is as though he has saved all of mankind.' (Surah Al-Ma'idah 5:32) There is no punishment upon either of them, and the blood money should be paid from the public treasury to the heirs of the deceased."
