“At Uhud, one of those killed was Mukhayriq. He was of Banu Tha‘laba b. al-Fityawn. On the day of the battle of Uhud he proclaimed, ‘O Jews, you have learned, I swear by God, that it is your duty to help Muhammad to victory.’ They responded, ‘But today is the sabbath’. ‘You shall have no sabbath,’ he insisted.
He then took his sword and equipment saying, ‘If I should fall, then my wealth goes to Muhammad to do with as he wishes.’
