يَا أَيُّهَا الَّذِينَ آمَنُواْ لاَ تَتَّخِذُواْ بِطَانَةً مِّن دُونِكُمْ لاَ يَأْلُونَكُمْ خَبَالاً وَدُّواْ مَا عَنِتُّمْ قَدْ بَدَتِ الْبَغْضَاء مِنْ أَفْوَاهِهِمْ وَمَا تُخْفِي صُدُورُهُمْ أَكْبَرُ قَدْ بَيَّنَّا لَكُمُ الآيَاتِ إِن كُنتُمْ تَعْقِلُونَ
[3:118]
O you who believe! do not take for intimate friends from among others than your own people; they do not fall short of inflicting loss upon you; they love what distresses you; vehement hatred has already appeared from out of their mouths, and what their breasts conceal is greater still; indeed, We have made the communications clear to you, if you will understand.
O ye who believe! Take not into your intimacy those outside your ranks: They will not fail to corrupt you. They only desire your ruin: Rank hatred has already appeared from their mouths: What their hearts conceal is far worse. We have made plain to you the Signs, if ye have wisdom.
O ye who believe! Take not for intimates others than your own folk, who would spare no pains to ruin you; they love to hamper you. Hatred is revealed by (the utterance of) their mouths, but that which their breasts hide is greater. We have made plain for you the revelations if ye will understand.
