Is it permissible to lease a property to a commercial bank for use as its headquarters?

If the bank is usurious, it is not permissible to rent property to it, as this involves 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, and they are all equal in sin. Providing a suitable place for usurers has a greater impact in supporting usury than merely writing a testimony about it, for persistence in usury means declaring war on Allah.
