Surah Al-Baqarah (The Cow), Verse 188

وَلَا تَاْكُلُوْۤا اَمْوَالَكُمْ بَیْنَكُمْ بِالْبَاطِلِ وَتُدْلُوْا بِهَاۤ اِلَی الْحُكَّامِ لِتَاْكُلُوْا فَرِیْقًا مِّنْ اَمْوَالِ النَّاسِ بِالْاِثْمِ وَاَنْتُمْ تَعْلَمُوْنَ 

Wa laa taakuloo amwaalakum bainakum bilbaatili wa tudloo bihaaa ilal hukkaami litaakuloo fareeqam min amwaalin naasi bil ismi wa antum ta'lamoon

“And do not eat up your property among yourselves for vanities, nor use it as bait for the judges, with intent that ye may eat up wrongfully and knowingly a little of (other) people's property.”

Quran 2:188 (Yusuf Ali Translation)
