Is providing assistance in researching information about bank mergers, which concern banks, considered forbidden due to its potential to constitute cooperation in sin?

The researcher's intention is to be considered. If the intention is to clarify the danger of usury and to strive to find permissible alternatives, then assisting him with his research is an act of righteousness and cooperation in piety. However, if he intends to promote usury, establish it, and advocate for it, or if his research contributes to this direction, then it is not permissible to assist him, due to the Almighty's saying: "And do not cooperate in sin and aggression." Furthermore, means have the rulings of their ends.
