Qur'an 4:144

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ ٱلْكَـٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۚ أَتُرِيدُونَ أَن تَجْعَلُوا۟ لِلَّهِ عَلَيْكُمْ سُلْطَـٰنًا مُّبِينًا

“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?”
