O you who believe! call to witness between you when death draws nigh to one of you, at the time of making the will, two just persons from among you, or two others from among others than you, if you are travelling in the land and the calamity of death befalls you; the two (witnesses) you should detain after the prayer; then if you doubt (them), they shall both swear by Allah, (saying): We will not take for it a price, though there be a relative, and we will not hide the testimony of Allah for then certainly we should be among the sinners.

Then if it becomes known that they both have been guilty of a sin, two others shall stand up in their place from among those who have a claim against them, the two nearest in kin; so they two should swear by Allah: Certainly our testimony is truer than the testimony of those two, and we have not exceeded the limit, for then most surely we should be of the unjust.
