Is one who presents a salary certificate at the request of an employee who needs it to submit to the bank for an interest-based loan sinful?

The framework of providing special certificates to an employee for the purpose of obtaining an interest-based loan falls under the category of assisting in sin, based on the Almighty’s saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."

Therefore, it is forbidden to engage in this work, and it must be abandoned immediately. For whoever fears Allah, He will make a way out for him and provide for him from where he does not expect.
