وَلَا تَأْكُلُوا أَمْوَالَكُمْ بَيْنَكُمْ بِالْبَاطِلِ وَتُدْلُوا بِهَا إِلَى الْحُكَّامِ لِتَأْكُلُوا فَرِيقًا مِنْ أَمْوَالِ النَّاسِ بِالْإِثْمِ وَأَنْتُمْ تَعْلَمُونَ
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: 

وَاستَغفِروا رَبَّكُم ثُمَّ توبوا إِلَيهِ ۚ إِنَّ رَبّى رَحيمٌ وَدودٌ
And ask forgiveness of your Lord and turn unto Him in repentance. Verily, my Lord is Most Merciful, Most Loving. Quran 11: 90
