Quran Al-Baqarah 2:188
وَلَا تَأۡكُلُوٓاْ أَمۡوَٰلَكُم بَيۡنَكُم بِٱلۡبَٰطِلِ وَتُدۡلُواْ بِهَآ إِلَى ٱلۡحُكَّامِ لِتَأۡكُلُواْ فَرِيقٗا مِّنۡ أَمۡوَٰلِ ٱلنَّاسِ بِٱلۡإِثۡمِ وَأَنتُمۡ تَعۡلَمُونَ ١٨٨
Translation
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].
