What is the ruling on an Islamic bank authorizing the orderer of a purchase (the customer) to buy the commodity, and also commissioning him to insure the goods under the pretext that the Central Bank of Algeria mandates it? And if this is impermissible, how can legitimate sources of funding for projects be found?

The bank's authorization of the purchase orderer to seize and sell the commodity to him has been permitted by some, provided it is not a ruse for usury, while others have prohibited it as a means to block the pretexts leading to usury. The insurance that the bank mandates appears to be commercial insurance, which is prohibited. If the Shariah controls are not met, then it is not permissible to proceed with it for the purpose of financing projects, because the lawful ways are many, and because "the Holy Spirit inspired in my soul that no soul shall die until it has fulfilled its sustenance and its term, so fear Allah and be graceful in seeking."
