Quran An-Nisa 4:144
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَتَّخِذُواْ ٱلۡكَٰفِرِينَ أَوۡلِيَآءَ مِن دُونِ ٱلۡمُؤۡمِنِينَۚ أَتُرِيدُونَ أَن تَجۡعَلُواْ لِلَّهِ عَلَيۡكُمۡ سُلۡطَٰنٗا مُّبِينًا ١٤٤
Translation
O you who have believed, do not take the disbelievers as allies instead of the believers. Do you wish to give Allāh against yourselves a clear case?
