Tafsir of Surah Al-Mumtahana 60:1
﴿بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا عَدُوِّي وَعَدُوَّكُمْ أَوْلِيَاءَ تُلْقُونَ إِلَيْهِم بِالْمَوَدَّةِ وَقَدْ كَفَرُوا بِمَا جَاءَكُم مِّنَ الْحَقِّ يُخْرِجُونَ الرَّسُولَ وَإِيَّاكُمْ أَن تُؤْمِنُوا بِاللَّهِ رَبِّكُمْ إِن كُنتُمْ خَرَجْتُمْ جِهَادًا فِي سَبِيلِي وَابْتِغَاءَ مَرْضَاتِي تُسِرُّونَ إِلَيْهِم بِالْمَوَدَّةِ وَأَنَا أَعْلَمُ بِمَا أَخْفَيْتُمْ وَمَا أَعْلَنتُمْ وَمَن يَفْعَلْهُ مِنكُمْ فَقَدْ ضَلَّ سَوَاءَ السَّبِيلِ﴾
Translation of the meaning
O you who have believed, do not take My enemies and your enemies as allies, extending to them affection while they have disbelieved in what came to you of the truth, having driven out the Prophet and yourselves [only] because you believe in Allāh, your Lord. If you have come out for jihād [i.e., fighting or striving] in My cause and seeking means to My approval, [take them not as friends]. You confide to them affection [i.e., instruction], but I am most knowing of what you have concealed and what you have declared. And whoever does it among you has certainly strayed from the soundness of the way.
