Will the prayer of the store manager, who has been harmed by us, against us and our families, be answered, knowing that we are compelling him to prove his innocence based on company documents to safeguard the employer's money?

If your judgment aligns with reality, then that is what is sought. But if it is otherwise, you will not be held accountable, because you judge by the data available to you, not by conjectures. Thus, the judge is correct in appearance. The supplication of those who are wronged against you unjustly will not be answered. And the trustworthy person is not liable for what is stolen without his negligence or transgression.
