Warning against cultural and political assimilation

ٱلَّذِينَ يَتَّخِذُونَ ٱلْكَـٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۚ أَيَبْتَغُونَ عِندَهُمُ ٱلْعِزَّةَ فَإِنَّ ٱلْعِزَّةَ لِلَّهِ جَمِيعًا

Those who take disbelievers as allies instead of the believers. Do they seek with them honor [through power]? But indeed, honor belongs to Allāh entirely.
