My father رحمه الله narrated to us. He said: `Ali b. Muhammad b. Qutayba narrated to us from Hamdan b. Sulayman from Nuh b. Shu`ayb from Muhammad b. Isma`il from Salih b. `Uqba from `Alqama from al-Sadiq Ja`far b. Muhammad عليه السلام. He said: A Bedouin came to the Prophet صلى الله عليه وعلى آله وسلم and demanded seventy silver coins from him – the price of a she-camel. So, the Prophet صلى الله عليه وعلى آله وسلم said to him: O Bedouin! Have you not collected that from me already? So, he said: No. So, the Prophet صلى الله عليه وعلى آله وسلم said to him: Surely, I have already paid you. So, the Bedouin said: I want a man to judge between you and me. So, the Prophet صلى الله عليه وعلى آله وسلم went with him and they appointed a man from Quraysh. So, the man said to the Bedouin: What is your claim against the Messenger of Allah? He said: Seventy silver coins – the price of a she-camel that I sold for him. So, he said: What do you say, O Messenger of Allah? So, he said: I have paid him. So, the Qurayshi man said: If you have given him his right, O Messenger of Allah, then either produce two witnesses to testify that you have paid him, or pay him the seventy [coins] that he has demanded from you. So, the Prophet صلى الله عليه وعلى آله وسلم stood up in anger, dragging his cloak. He said: By Allah! I will choose someone who will judge between us by the judgment of Allah. So, they appointed Amir al-Mu’minin `Ali b. Abi Talib عليه السلام, who said to the Bedouin: What is your claim against the Messenger of Allah? He said: Seventy silver coins – the price of a she-camel that I sold for him. He said: What do you say, O Messenger of Allah? He said: I have paid him. So, he said: O Bedouin! Surely, the Messenger of Allah صلى الله عليه وعلى آله وسلم says that he has paid you. Is he telling the truth? He said: No, he did not pay me. So, Amir al-Mu’minin عليه السلام unsheathed his sword from its scabbard and struck the neck of the Bedouin. So, the Messenger of Allah صلى الله عليه وعلى آله وسلم said: O `Ali! Why did you kill the Bedouin? He said: Because he belied you, O Messenger of Allah, and when one belies you, his blood becomes permissible and his killing becomes obligatory. So, the Prophet صلى الله عليه وعلى آله وسلم said: O `Ali! By He who raised me as a prophet in truth, you have not made a mistake in applying the judgment of Allah regarding him. [However,] do not repeat this again.
