Quran

 3:28

لَا يَتَّخِذِ الْمُؤْمِنُونَ الْكَافِرِينَ أَوْلِيَاءَ مِنْ دُونِ الْمُؤْمِنِينَ ۖ وَمَنْ يَفْعَلْ ذَٰلِكَ فَلَيْسَ مِنَ اللَّهِ فِي شَيْءٍ إِلَّا أَنْ تَتَّقُوا مِنْهُمْ تُقَاةً ۗ وَيُحَذِّرُكُمُ اللَّهُ نَفْسَهُ ۗ وَإِلَى اللَّهِ الْمَصِيرُ ﴿٢٨﴾

28. Believers shall not take disbelievers for allies instead of believers. Whoever does that has nothing to do with Allah, unless you cautiously protect yourself from them. Allah warns you of Himself. And to Allah is the destination.
