The Table Spread - 5:106
"Believers, when death comes to one of you, let two just witnesses be present from among you at the time of the will. And if death comes to you while you are traveling, two of you who are not of you. If you are in doubt, detain the witnesses after the prayer and say in the name of Allah: "We will not exchange our testimony for anything, not even relatives, nor conceal the testimony of Allah. Otherwise, we shall be among the sinners."
