What is the ruling on depositing money in a usurious bank with the intention of protecting it from theft, provided that the amount will be transferred to an Islamic bank later? Is this considered assisting in sin, and does one fall under the curse, "May Allah curse the one who consumes Riba, the one who feeds it, its two witnesses, and its scribe"?

It is permissible to deposit money in a usurious bank out of necessity, such as fear of theft or loss, and the absence of an Islamic bank, provided that one limits it to a current account and withdraws the money when it is possible to safeguard it by other means. This is based on the Almighty's saying: "But whoever is forced by necessity, neither intending to disobey nor transgressing, there is no sin upon him. Indeed, Allah is Forgiving and Merciful."
