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.

And this is a Book We have revealed, blessed, verifying that which is before it, and that you may warn the metropolis and those around her; and those who believe in the hereafter believe in it, and they attend to their prayers constantly.
