2. Al-Baqara (The Cow)

Surah: 2   Aya: 275

275. Allatheena ya/kuloona alrriba la yaqoomoona illa kama yaqoomu allathee yatakhabbatuhu alshshaytanu mina almassi thalika bi-annahum qaloo innama albayAAu mithlu alrriba waahalla Allahu albayAAa waharrama alrriba faman jaahu mawAAithatun min rabbihi faintaha falahu ma salafa waamruhu ila Allahi waman AAada faola-ika as-habu alnnari hum feeha khalidoona
  

  Translation

275. Those who eat Ribâ (usury) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitân (Satan) leading him to insanity. That is because they say: "Trading is only like Ribâ (usury)," whereas Allâh has permitted trading and forbidden Ribâ (usury). So whosoever receives an admonition from his Lord and stops eating Ribâ (usury) shall not be punished for the past; his case is for Allâh (to judge); but whoever returns [to Ribâ (usury)], such are the dwellers of the Fire - they will abide therein.
