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 wherefore was there not a town which should believe so that their belief should have profited them but the people of Yunus? When they believed, We removed from them the chastisement of disgrace in this world's life and We gave them provision till a time.
