Is my work in preparing project budgets that include calculating usurious interest for banks, bank letter of credit commissions, commercial insurance costs, and bribes under the name of commissions and facilities, considered aiding in usury and bribery, knowing that my work ends upon submitting the budget and I do not participate in executing the project?

You are not permitted to do this work if it involves assisting with and condoning usury and forbidden transactions, due to the Almighty's saying: "And do not cooperate in sin and aggression." The Prophet, peace and blessings be upon him, cursed the devourer of usury, its payer, its scribe, and its two witnesses; they are all equal. Al-Nawawi said: "In it is the prohibition of assisting in falsehood."
