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.

Those who keep aloof from the great sins and the indecencies but the passing idea; surely your Lord is liberal in forgiving. He knows you best when He brings you forth from the earth and when you are embryos in the wombs of your mothers; therefore do not attribute purity to your souls; He knows him best who guards (against evil).
