What is the ruling on photographing private documents belonging to the Agricultural Development Bank at the request of a bank employee?

It is not permissible to photograph documents for the Agricultural Development Bank if these documents are usurious contracts, because this constitutes cooperation in sin. The Prophet, peace and blessings be upon him, cursed the one who consumes usury, the one who feeds it, its scribe, and its two witnesses. However, if the documents do not pertain to usurious matters, then it is permissible to photograph them.
