O you who believe[d]! When you contract with one another any debt for a term fixed then write it. And let write between you a scribe in justice. And not (should) refuse a scribe that he writes as (has) taught him Allah. So let him write and let dictate the one on whom (is) the right and let him fear Allah, his Lord, and (let him) not diminish from it anything. Then if is the one on him (is) the right, (of) limited understanding, or weak, or not capable that (can) dictate he, then let dictate his guardian with justice. And call for evidence two witnesses among your men. And if not there are two men then one man and two women of whom you agree of [the] witnesses, (so) that (if) [she] errs, one of the two, then will remind one of the two the other. And not (should) refuse the witnesses when that they are called. And not (be) weary that you write it - small or large for its term. That (is) more just near Allah, and more upright for evidence and nearer that not you (have) doubt, except that be a transaction present, you carry out among you, then not on you any sin that not you write it. And take witness when you make commercial transactio And not (should) be harmed (the) scribe and not (the) witness, and if you do, then indeed it (is) sinful conduct for you, and fear Allah. And teaches Allah. And Allah of every thing (is) All-Knower.
