When Tamim and 'Adi returned conveying the property of the deceased, they claimed that they had lost a silver bowl with gold engraving. Allah's Messenger () made them take an oath (to confirm their claim), and then the bowl was found in Makkah with some people who claimed that they had bought it from Tamim and 'Adu, Then two witnesses from the relatives of the deceased got up and swore that their witnesses were more valid than the witnesses of  'Adi and Tamim, and that the bowl belonged to their deceased fellow. So, this verse was revealed in connection with this case ; 'O you who believe! When death approached any of you ...'," (V 5:                     106)
