Quran 3:28 from Surah Aal-i-Imraan on Divine Marvels.
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
English translation: (Let) not take the believers the disbelievers (as) allies from instead of the believers And whoever does that then not he (has) from Allah [in] anything except that you fear from them (as) a precaution And warns you Allah (of) Himself and to Allah (is) the destination
