Qur'an 3:28 · Aal-i-Imraan

لَّا يَتَّخِذِ ٱلْمُؤْمِنُونَ ٱلْكَٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۖ وَمَن يَفْعَلْ ذَٰلِكَ فَلَيْسَ مِنَ ٱللَّهِ فِى شَىْءٍ إِلَّآ أَن تَتَّقُوا۟ مِنْهُمْ تُقَىٰةًۭ ۗ وَيُحَذِّرُكُمُ ٱللَّهُ نَفْسَهُۥ ۗ وَإِلَى ٱللَّهِ ٱلْمَصِيرُ

(28) Let not believers take disbelievers as allies [i.e., supporters or protectors] rather than believers. And whoever [of you] does that has nothing [i.e., no association] with Allāh, except when taking precaution against them in prudence.[122] And Allāh warns you of Himself, and to Allāh is the [final] destination.
