Quran

 2:120

وَلَنْ تَرْضَىٰ عَنْكَ الْيَهُودُ وَلَا النَّصَارَىٰ حَتَّىٰ تَتَّبِعَ مِلَّتَهُمْ ۗ قُلْ إِنَّ هُدَى اللَّهِ هُوَ الْهُدَىٰ ۗ وَلَئِنِ اتَّبَعْتَ أَهْوَاءَهُمْ بَعْدَ الَّذِي جَاءَكَ مِنَ الْعِلْمِ ۙ مَا لَكَ مِنَ اللَّهِ مِنْ وَلِيٍّ وَلَا نَصِيرٍ ﴿١٢٠﴾

120. The Jews and the Christians will never approve of you: unless you follow their creed. Say, “Allah’s guidance is the guidance.” Should you follow their desires, after the knowledge that has come to you, you will have in Allah neither guardian nor helper.
