Surat Aal-i-Imraan (The Family of Imraan) - آل عمران

لَّا يَتَّخِذِ ٱلْمُؤْمِنُونَ ٱلْكَٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ وَمَن يَفْعَلْ ذَٰلِكَ فَلَيْسَ مِنَ ٱللَّهِ فِى شَىْءٍ إِلَّآ أَن تَتَّقُوا۟ مِنْهُمْ تُقَىٰةً وَيُحَذِّرُكُمُ ٱللَّهُ نَفْسَهُۥ وَإِلَى ٱللَّهِ ٱلْمَصِيرُ ﴿٢٨﴾

Let not the believers take the unbelievers for friends rather than believers; and whoever does this, he shall have nothing of (the guardianship of) Allah, but you should guard yourselves against them, guarding carefully; and Allah makes you cautious of (retribution from) Himself; and to Allah is the eventual coming.
