Quran

 3:118

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا بِطَانَةً مِنْ دُونِكُمْ لَا يَأْلُونَكُمْ خَبَالًا وَدُّوا مَا عَنِتُّمْ قَدْ بَدَتِ الْبَغْضَاءُ مِنْ أَفْوَاهِهِمْ وَمَا تُخْفِي صُدُورُهُمْ أَكْبَرُ ۚ قَدْ بَيَّنَّا لَكُمُ الْآيَاتِ ۖ إِنْ كُنْتُمْ تَعْقِلُونَ ﴿١١٨﴾

118. O you who believe! Do not befriend outsiders who spare no effort to ruin you. They love to see you suffer. Hatred is apparent in what they say, but what their hearts conceal is worse. We made the communications clear for you—if you understand.
