بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ عَدُوِّى وَعَدُوَّكُمْ أَوْلِيَآءَ تُلْقُونَ إِلَيْهِم بِٱلْمَوَدَّةِ وَقَدْ كَفَرُوا۟ بِمَا جَآءَكُم مِّنَ ٱلْحَقِّ يُخْرِجُونَ ٱلرَّسُولَ وَإِيَّاكُمْ ۙ أَن تُؤْمِنُوا۟ بِٱللَّهِ رَبِّكُمْ إِن كُنتُمْ خَرَجْتُمْ جِهَٰدًۭا فِى سَبِيلِى وَٱبْتِغَآءَ مَرْضَاتِى ۚ تُسِرُّونَ إِلَيْهِم بِٱلْمَوَدَّةِ وَأَنَا۠ أَعْلَمُ بِمَآ أَخْفَيْتُمْ وَمَآ أَعْلَنتُمْ ۚ وَمَن يَفْعَلْهُ مِنكُمْ فَقَدْ ضَلَّ سَوَآءَ ٱلسَّبِيلِ
O ye who believe! Choose not My enemy and your enemy for allies. Do ye give them friendship when they disbelieve in that truth which hath come unto you, driving out the messenger and you because ye believe in Allah, your Lord? If ye have come forth to strive in My way and seeking My good pleasure, (show them not friendship). Do ye show friendship unto them in secret, when I am Best Aware of what ye hide and what ye proclaim? And whosoever doeth it among you, he verily hath strayed from the right way.
Surah Al-Mumtahana(60:1)
