Al-Mumtahinah
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَتَّخِذُواْ عَدُوِّي وَعَدُوَّكُمۡ أَوۡلِيَآءَ تُلۡقُونَ إِلَيۡهِم بِٱلۡمَوَدَّةِ وَقَدۡ كَفَرُواْ بِمَا جَآءَكُم مِّنَ ٱلۡحَقِّ يُخۡرِجُونَ ٱلرَّسُولَ وَإِيَّاكُمۡ أَن تُؤۡمِنُواْ بِٱللَّهِ رَبِّكُمۡ إِن كُنتُمۡ خَرَجۡتُمۡ جِهَٰدٗا فِي سَبِيلِي وَٱبۡتِغَآءَ مَرۡضَاتِيۚ تُسِرُّونَ إِلَيۡهِم بِٱلۡمَوَدَّةِ وَأَنَا۠ أَعۡلَمُ بِمَآ أَخۡفَيۡتُمۡ وَمَآ أَعۡلَنتُمۡۚ وَمَن يَفۡعَلۡهُ مِنكُمۡ فَقَدۡ ضَلَّ سَوَآءَ ٱلسَّبِيلِ
O you who believe! Take not My enemies and your enemies (i.e. disbelievers and polytheists, etc.) as friends, showing affection towards them, while they have disbelieved in what has come to you of the truth (i.e. Islamic Monotheism, this Quran, and Muhammad SAW), and have driven out the Messenger (Muhammad SAW) and yourselves (from your homeland) because you believe in Allah your Lord! If you have come forth to strive in My Cause and to seek My Good Pleasure, (then take not these disbelievers and polytheists, etc., as your friends). You show friendship to them in secret, while I am All-Aware of what you conceal and what you reveal. And whosoever of you (Muslims) does that, then indeed he has gone (far) astray, (away) from the Straight Path.
إِن يَثۡقَفُوكُمۡ يَكُونُواْ لَكُمۡ أَعۡدَآءٗ وَيَبۡسُطُوٓاْ إِلَيۡكُمۡ أَيۡدِيَهُمۡ وَأَلۡسِنَتَهُم بِٱلسُّوٓءِ وَوَدُّواْ لَوۡ تَكۡفُرُونَ
Should they gain the upper hand over you, they would behave to you as enemies, and stretch forth their hands and their tongues against you with evil, and they desire that you should disbelieve.
