Surah 5

Surah 5:106

"You who believe! When death approaches one of you, the testimony among you at the time (of making) bequests will be (that of) two just men of you, or two others of (a people) other than you, if you strike forth on the earth and the smiting of death smites you. Detain them both after the prayer, and let them both swear by God, if you have your doubts (about them): ‘We will not sell it for a price, even if he happens to be a family member, and we will not conceal the testimony of God. Surely then we would indeed be among the sinners.’"
