The Dangers of Riba (Usury) by Imam Karim AbuZaid

Verse 275: Those who eat Riba (usury) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitan (Satan) leading him to insanity. That is because they say: "Trading is only like Riba (usury)," whereas Allah has permitted trading and forbidden Riba (usury). So whosoever receives an admonition from his Lord and stops eating Riba (usury) shall not be punished for the past; his case is for Allah (to judge); but whoever return [to Riba (usury)], such are the dwellers of the Fire -- they will abide therein forever. Verse 276. Allah will destroy Riba (usury) and will give increase for Sadaqat (deeds of charity, alms, etc.) And Allah likes not the disbelievers, sinners. Verse 277. Truly those who believe, and do deeds of righteousness, and perform As-Salat (Iqamat-as-Salat), and give Zakat, they will have their reward with their Lord. On them shall be no fear, nor shall they grieve. Verse 278. O you who believe! Be afraid of Allah and give up what remains (due to you) from Riba (usury) (from now onward), if you are (really) believers. Verse 279. And if you do not do it, then take a notice of war from Allah and His Messenger (PBUH) [1] but if you repent, you shall have your capital sums. Deal not unjustly (by asking more than your capital sums), and you shall not be dealt with unjustly (by receiving less than your capital sums).
