Is it permissible to work in a usurious bank in the field of computers and technology for the purpose of returning to a Muslim country?

The emigration (Hijrah) of a Muslim from a land of disbelief (Kufr) to a land of Islam is obligatory if they fear temptation (fitna) for themselves and are unable to openly practice their religious rituals. It is recommended if they are able to practice them openly and do not fear temptation.

If the person returning to their homeland finds no work except what is unlawful, they should remain in their current country, because avoiding the unlawful takes precedence over the recommended. However, if the emigration is obligatory, then they must emigrate and seek lawful work. If they find no work except an unlawful one in an interest-based bank and have no other source of livelihood, then working in an interest-based bank is considered less harmful than remaining in a land where they fear for their religion. In cases where multiple harms converge, the least harmful option is chosen.
