An-Nisa' - 4:29

يَا أَيُّهَا الَّذِينَ آمَنُواْ لاَ تَأْكُلُواْ أَمْوَالَكُمْ بَيْنَكُمْ بِالْبَاطِلِ إِلاَّ أَن تَكُونَ تِجَارَةً عَن تَرَاضٍ مِّنكُمْ وَلاَ تَقْتُلُواْ أَنفُسَكُمْ إِنَّ اللّهَ كَانَ بِكُمْ رَحِيمًا
[4:29]
O you who believe! do not devour your property among yourselves falsely, except that it be trading by your mutual consent; and do not kill your people; surely Allah is Merciful to you.
O ye who believe! Eat not up your property among yourselves in vanities: But let there be amongst you Traffic and trade by mutual good-will: Nor kill (or destroy) yourselves: for verily Allah hath been to you Most Merciful!
O ye who believe! Squander not your wealth among yourselves in vanity, except it be a trade by mutual consent, and kill not one another. Lo! Allah is ever Merciful unto you.
