Surah Al-Baqarah — Ayah 188 (2:188)
وَلَا تَأۡكُلُوٓاْ أَمۡوَٰلَكُم بَيۡنَكُم بِٱلۡبَٰطِلِ وَتُدۡلُواْ بِهَآ إِلَى ٱلۡحُكَّامِ لِتَأۡكُلُواْ فَرِيقٗا مِّنۡ أَمۡوَٰلِ ٱلنَّاسِ بِٱلۡإِثۡمِ وَأَنتُمۡ تَعۡلَمُونَ ١٨٨
English translation (Saheeh International)
And do not consume one another's wealth unjustly or send it [in bribery] to the rulers in order that [they might aid] you [to] consume a portion of the wealth of the people in sin, while you know [it is unlawful].
Brief commentary
Do not take each other’s wealth unjustly: robbing it or taking it by force or by cheating, and then making it a legal dispute in order to obtain other’s wealth wrongfully, when you know that Allah has prohibited that. Committing a sin knowingly is the worst of things and has the greatest of punishments.
