Does the renovation of the decor of usurious bank branches make the work impermissible or permissible?

Usury is a grave sin, and severe warnings have been issued concerning it. Whoever does not abandon what remains of usury should be prepared for a war from Allah and His Messenger. 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. He considered one dirham of usury to be more severe in the sight of Allah than thirty-six acts of adultery.

Therefore, it is not permissible to assist in usury in any way, such as building usurious banks, or renovating or decorating them, because this constitutes aiding in sin and aggression.

Thus, if your work is related to the renovation of the bank, it is forbidden. However, if it is in another department that has no connection to this, then there is no harm upon you.
