Surah Al-Imran, ayah 118

3:118

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَتَّخِذُواْ بِطَانَةٗ مِّن دُونِكُمۡ لَا يَأۡلُونَكُمۡ خَبَالٗا وَدُّواْ مَا عَنِتُّمۡ قَدۡ بَدَتِ ٱلۡبَغۡضَآءُ مِنۡ أَفۡوَٰهِهِمۡ وَمَا تُخۡفِي صُدُورُهُمۡ أَكۡبَرُۚ قَدۡ بَيَّنَّا لَكُمُ ٱلۡأٓيَٰتِۖ إِن كُنتُمۡ تَعۡقِلُونَ ١١٨

Yā'ayyuhal-ladhīna āmanū lā tattakhidhū bitānatam min dūnikum lā ya'lūnakum khabālan waddū mā 'anittum qad badatil-baghdā'u min afwāhihim wamā tukhfī sudūruhum akbaru qad bayyannā lakumul-āyāti in kuntum ta'qilūn

O you who have believed, do not take as intimates those other than yourselves [i.e., believers], for they will not spare you [any] ruin. They wish you would have hardship. Hatred has already appeared from their mouths, and what their breasts conceal is greater. We have certainly made clear to you the signs, if you will use reason.
