Hadith.3425 - A Bedouin came to the Prophet, peace be upon him and his family, and claimed seventy dirhams as the price of a she-camel he had sold to Him (sw). The Prophet (sw) said: "I have paid you." The Bedouin said: "Appoint someone between me and you who will judge between us." Then, a man from Quraysh approached, and the Messenger of Allah (swt), peace be upon him and his family, said: "Judge between us." The man asked the Bedouin: "What is your claim against the Messenger of Allah (swt)?" He replied: "Seventy dirhams, the price of a she-camel I sold to Him (sw)." The judge asked: "What do you say, O Messenger of Allah (swt)?" The Prophet (sw) said: "I have paid him." The judge then asked the Bedouin: "What do you say?" The Bedouin replied: "He (sw) has not paid me." The judge said to the Messenger of Allah (swt), peace be upon him and his family: "Do you have any evidence that you have paid him?" The Prophet (sw) said: "No." The judge then said to the Bedouin: "Will you swear that you have not received your due and then take it?" The Bedouin replied: "Yes." Then the Messenger of Allah (swt), peace be upon him and his family, said: "I will indeed take this matter for judgment to a man who judges between us with the judgment of Allah (swt), the Mighty and Majestic." The Messenger of Allah (swt), peace be upon him and his family, went to Imam Ali ibn Abi Talib (as), accompanied by the Bedouin. Imam Ali ibn Abi Talib (as) said: "What is the matter, O Messenger of Allah (swt)?" He (sw) said: "O Abu al-Hasan (as), judge between me and this Bedouin." Imam Ali ibn Abi Talib (as) said: "O Bedouin, what is your claim against the Messenger of Allah (swt)?" The Bedouin replied: "Seventy dirhams, the price of a she-camel I sold to him (sw)." Imam Ali ibn Abi Talib (as) asked: "What do you say, O Messenger of Allah (swt)?" The Prophet, peace be upon him and his family, said: "I have paid him its price." Imam Ali ibn Abi Talib (as) said: "O Bedouin, has the Messenger of Allah (swt), peace be upon him and his family, spoken the truth in what He (sw) said?" The Bedouin replied: "No, He (sw) has not paid me anything." Imam Ali ibn Abi Talib (as), then drew his sword and struck his neck. The Messenger of Allah (swt), peace be upon him and his family, said: "Why did you do that, O Ali (as)?" Imam Ali ibn Abi Talib (as) replied: "O Messenger of Allah (swt), we believe you concerning Allah's (swt) commands and prohibitions, and regarding Paradise and Hell, reward and punishment, and the revelation of Allah (swt), the Mighty and Majestic. Should we then not believe you concerning the price of this Bedouin's she-camel? I killed him because he denied you when I asked him, 'Has the Messenger of Allah (swt) spoken the truth in what he said?' and he replied: 'No, he has not paid me anything.'" The Messenger of Allah (swt), peace be upon him and his family, said: "You have done right, O Ali (as), but do not repeat this again." Then, He (sw) turned to the Qurayshi man who had followed him and said: "This is the judgment of Allah (swt), not what you had judged."
