It was narrated that an armor was stolen from the house of a Muslim man from Medina. This incident shaked the whole city. Who could have done such evil in the city of Prophet Muhammad ?
While the investigation was in progress, the thief put the armor in the house of a Jew.
Someone said that he saw a man named Tuma bin Ubayriq steal the armor. Its owner approached the Prophet (peace be on him) and expressed his suspicion about Tumah. But Tuma and his kinsmen colluded to ascribe the guilt to the Jew.
To ascertain the truth, the Prophet sent people to look in Tuma’s house. The armor was not there.
The armor was found in the house of the Jew !
When the Jew concerned was asked about the matter he pleaded that he was not guilty. Tuma's supporters, on the other hand, waged a vigorous propaganda campaign to save Tuma's skin. They argued that the Jew, who had denied the Truth and disbelieved in God and the Prophet (peace be on him), was absolutely untrustworthy, and his statement ought to be rejected outright.
But something happened. God sent the Angel Gabriel to the Prophet to declare that the Jewish man was innocent, and it was indeed Tuma who stole the armor. God revealed in the Qur’an:
“(O Messenger!) We have revealed to you this Book with the Truth so that you may judge between people in accordance with what Allah has shown you. So do not dispute on behalf of the dishonest"4:105
