Is it permissible to work in a usurious bank if this is a person's specialization?

Working in usurious banks is forbidden by Islamic law, based on the texts of the Qur'an, the Sunnah, and the consensus of Muslims. This is because Allah has forbidden usury, and His Messenger, peace be upon him, cursed the one who consumes it, the one who pays it, its scribe, and its two witnesses. A Muslim must leave work in these institutions and seek permissible employment in non-usurious financial institutions, for Allah Almighty provides for those who fear Him from where they do not expect.
