Believers, when death approaches you, let two just men from among you act as witnesses when you make your testaments; or two men from another tribe, if the calamity of death overtakes you while you are travelling in the land. Detain them after prayers, and if you doubt their honesty, let them swear by God, "We will not sell our testimony for any price, even to a kinsman. And we will not conceal the testimony of God. If we did, we would indeed be guilty of sin."
