Is it permissible to participate in a competition whose prizes are offered by a usurious bank?

The scenarios for competitions can be summarized as follows:

1. First Scenario: If the participant deposits their account in a bank and the questions are not related to Islamic sciences, this is unlawful from several perspectives: depositing money in an interest-based bank, receiving compensation for an impermissible competition, gambling (as the bank benefits from attracting customers), usury (because opening the account brings a benefit), and usually, the prizes are from prohibited interest-based earnings.

2. Second Scenario: If the participant does not deposit their account in a bank, this is unlawful because it involves receiving compensation for an impermissible competition, and accepting money of which most is unlawful.

3. Third Scenario: If the participant does not deposit their account in a bank and the competition is in Islamic sciences, this is generally unlawful because the prizes are from interest-based earnings. However, if it is known that the prizes are not from unlawful money, then there is no objection, with a preference for the permissibility of receiving compensation for competitions in Islamic sciences, which is the view of the Hanafis and those who agree with them.
