Kenana ibn al-Rabi, when asked about the treasure they brought with them at the time of leaving Medina, denied having any such treasure. He was told that in case the treasure could be found hidden, he would face death-penalty for his false promise. Kenana agreed to this. A Jew told Muhammad that he had seen Al-Rabi near a certain ruin every morning. When the ruin was excavated, it was found to contain some of the treasure. Kenana was executed as a result. Shibli Nomani rejects this account, and argues that Kenana was killed because he had earlier murdered Mahmoud ibn Maslamah, brother of Muhammad ibn Maslamah.
