Is an employee who stores usurious loan documents and writes the financial liabilities of workers, which include usurious transactions, included in the Hadith that curses usury, its agent, its scribe, and its two witnesses?

You are not at fault for what you mentioned, as that is not a form of assisting with a usurious loan. Rather, it is akin to recording information about an individual and informing that he has borrowed with usury. This, by itself, is not sinful. We advise you to counsel those who borrow with usury and remind them of its ruling.
