What is the ruling on working at Nasser Social Bank?

If the bank has Islamic branches that adhere to Sharia principles, then there is no objection to working in one of them. As for working in a usurious bank, even if it is in a field other than usurious transactions, it is not permissible, because it is considered assisting in sin and transgression. Allah Almighty says: "And do not cooperate in sin and aggression." Furthermore, 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, saying, "They are all equal." This indicates the prohibition of assisting in falsehood in any way, and the employee in a usurious bank will inevitably be either a scribe, a witness, or an assistant to usury.
