﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ بِطَانَةًۭ مِّن دُونِكُمْ لَا يَأْلُونَكُمْ خَبَالًۭا وَدُّوا۟ مَا عَنِتُّمْ قَدْ بَدَتِ ٱلْبَغْضَآءُ مِنْ أَفْوَٰهِهِمْ وَمَا تُخْفِى صُدُورُهُمْ أَكْبَرُ ۚ قَدْ بَيَّنَّا لَكُمُ ٱلْءَايَٰتِ ۖ إِن كُنتُمْ تَعْقِلُونَ ﴾

“O YOU who have attained to faith! Do not take for your bosom-friends people who are not of your kind. They spare no effort to corrupt you; they would love to see you in distress. Vehement hatred has already come into the open from out of their mouths, but what their hearts conceal is yet worse. We have indeed made the signs [thereof] clear unto you, if you would but use your reason.”

O you who believe do not take as intimates as sincere friends revealing to them your secret thoughts anyone apart from yourselves from among the Jews Christians and the hypocrites; such men spare nothing to ruin you khabālan is in the accusative because the preposition that usually precedes it sc. fī’l-khabāl has been omitted that is to say they would not be remiss about corrupting you; they would love they wish for you to suffer al-‘anat means extreme hardship. Hatred enmity towards you is revealed it is manifested by their mouths by sowing discord among you and informing the idolaters of your secret plans; and what their breasts conceal of enmity is yet greater. Now We have made clear to you the signs of their enmity; if you understand this then do not befriend them.
