КОРАН (английский перевод) - 5.106

Believers, if you are traveling in the land and the affliction of death befalls you, at the bequeathing testimony shall be two just men from among you, or two others from other than you. You shall detain both after the prayer, and they shall swear by Allah if you are doubtful: 'We will not sell it for a price, even though it were a near kinsmen, nor will we hide the testimony of Allah, because then we would surely be among the sinful. '
