Allah Almighty says: {Those who consume usury will not stand [on the Day of Resurrection] except like those being beaten by Satan. That is because they say, “Trade is just like usury.” But Allah has permitted trade and forbidden usury. Whoever desists because of receiving admonition from his Lord may keep his past gains, and his case is left to Allah. But whoever returns to it, they are the people of the Fire; they will abide therein forever. Allah destroys usury} To the verse that says: {O you who believe, fear Allah and give up usury that is still due} [Surat al-Baqarah: 275-278]
1) Riba is prohibited in all its forms and types, because it is one of the gravest major sins and prohibiting it aims at blocking the ways to corruption.
2) Islam encourages seeking lawful ways of earning, like trade, in order to attain blessing.
3) Islam urges mutual charity among Muslims and offering facilitations to debtors and helping them.
there are many famous authentic ones, like the Hadīth of Abu Hurayrah (may Allah be pleased with him) cited in the previous chapter.
1615/1- Ibn Mas‘ūd (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) cursed the one who consumes Riba and the one who pays it. [Narrated by Muslim]
At-Tirmidhi and others added: “and its two witnesses and the one who writes it down.”
1) Riba is prohibited as it is one of the major sins. The Messenger of Allah (may Allah’s peace and blessings be upon him) cursed the one who deals with it and all those who cooperate in that sin.
2) The one who helps or participates in sin is as sinful as the original sinner and deserves the same punishment.
