If you are (in circumstances like being) on a journey and cannot find a scribe, then a pledge in hand will suffice. But if you trust one another, let him (the debtor) who is trusted fulfill his trust, and let him act in piety and keep from disobedience to God, his Lord (by fulfilling the conditions of the contract). And do not conceal the testimony; he who conceals it, surely his heart (which is the center of faith) is contaminated with sin. God has full knowledge of what you do.
