it down between you justly, and the scribe may not refuse to write it down according to what Allah has taught him;

Believers! Whenever you contract a debt from one another for a known term, commit it to writing. Let a scribe write it down between you justly, and the scribe may not refuse to write it down according to what Allah has taught him; so let him write, and let the debtor dictate; and let him fear Allah, his Lord, and curtail no part of it. If the debtor be feeble minded, weak, or incapable of dictating, let his guardian dictate equitably, and call upon two of your men as witnesses; but if two men are not there, then let there be one man and two women as witnesses from among those acceptable to you so that if one of the two women should fail to remember, the other might remind her. Let not the witnesses refuse when they are summoned (to give evidence). Do not show slackness in writing down the transaction, whether small or large, along with the term of its payment. That is fairest in the sight of Allah; it is best for testimony and is more likely to exclude all doubts. If it be a matter of buying and selling on the spot, it is not blameworthy if you do not write it down; but do take witnesses when you settle commercial transactions with one another. And the scribe or the witness may be done no harm. It will be sinful if you do so. Beware of the wrath of Allah. He teaches you the Right Way and has full knowledge of everything.
