Al 'Imran, 28 Ayah
3:28
لَّا يَتَّخِذِ ٱلۡمُؤۡمِنُونَ ٱلۡكَٰفِرِينَ أَوۡلِيَآءَ مِن دُونِ ٱلۡمُؤۡمِنِينَۖ وَمَن يَفۡعَلۡ ذَٰلِكَ فَلَيۡسَ مِنَ ٱللَّهِ فِي شَيۡءٍ إِلَّآ أَن تَتَّقُواْ مِنۡهُمۡ تُقَىٰةٗۗ وَيُحَذِّرُكُمُ ٱللَّهُ نَفۡسَهُۥۗ وَإِلَى ٱللَّهِ ٱلۡمَصِيرُ ٢٨
Lā Yattakhidhi Al-Mu'uminūna Al-Kāfirīna 'Awliyā'a Min Dūni Al-Mu'uminīna ۖ Wa Man Yaf`al Dhālika Falaysa Mina Al-Lahi Fī Shay'in 'Illā 'An Tattaqū Minhum Tuqāatan ۗ Wa Yuĥadhdhirukumu Al-Lahu Nafsahu ۗ Wa 'Ilá Al-Lahi Al-Maşīru
Let not believers take disbelievers as allies rather than believers. And whoever [of you] does that has nothing with Allah, except when taking precaution against them in prudence. And Allah warns you of Himself, and to Allah is the [final] destination.
