In his response to your question, Prof. Dr. Monzer Kahf, Professor of Islamic Finance and Economics at Qatar Faculty of Islamic Studies, states:

Riba (usury) is one of the worst sins in Islam. It is the only one about which the Qur’an has declared a war from Allah and His Messenger.

Allah Almighty knows best.
