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

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. And Allāh warns you of Himself, and to Allāh is the [final] destination.

The believers should not make the disbelievers their allies rather than other believers- anyone who does such a thing will isolate himself completely from God- except when you need to protect yourselves from them. God warns you to beware of Him: the Final Return is to God.
— M. A. S. Abdel Haleem
Let not the believers take the disbelievers as Auliyâ (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allâh in any way, except if you indeed fear a danger from them. And Allâh warns you against Himself (His punishment), and to Allâh is the final return.
