(Riba is a concept in Islamic banking that refers to charged interest. It is forbidden under Sharia, Islamic religious law, because it is thought to be exploitive. Depending on the interpretation, riba may only refer to excessive interest; however to others, the whole concept of interest is riba, and thus is unlawful.)
Qom- DarolErfan/ the researcher, exegete and scholar of the Quranic sciences pointed out that achieving the paradise requires financial, existential and moral endeavor. He also added: committing sin is hard but repenting from the sins is even harder, but committing or doing Riba has no repentance and the sin of Riba can not be eliminated from the file of our actions by crying and resorting.
The commander of faithful (AS) says about those who have a strong and solid faith about paradise and hell and have gained this firm belief either by acquiring the principles of religion or by listening to divines issues from the pure people: these type of people have a positive business due to their faith in paradise and hell; their positive business is that they make a lot of efforts so as to achieve paradise, and the holy Quran has talked about this effort in several sections.
