Is it permissible to resort to a usurious loan to finance a project that is the sole source of livelihood, given the unavailability of alternatives and the dire need for money?

It is not permissible to resort to usury and forbidden transactions unless there is a necessity that allows committing the prohibited, as Allah Almighty says: "And He has explained to you in detail what He has forbidden you, except that which you are compelled to." Usury is not a solution to problems; rather, it exacerbates them. Sustenance comes from Allah alone, and whoever fears Allah - He will make for him a way out and provide for him from where he does not expect.

You should rely on Allah, and frequently make supplications and seek forgiveness. Among the narrated supplications for repaying debt are: "O Allah, I seek refuge in You from anxiety and sorrow, and I seek refuge in You from inability and laziness, and I seek refuge in You from cowardice and stinginess, and I seek refuge in You from the burden of debt and the domination of men," and "O Allah, suffice me with Your lawful against Your unlawful, and enrich me by Your favor beyond anyone else."
