وَلَنْ تَرْضٰى عَنْكَ الْيَهُوْدُ وَلَا النَّصٰرٰى حَتّٰى تَتَّبِعَ مِلَّتَهُمْ ۗ قُلْ اِنَّ هُدَى اللّٰهِ هُوَ الْهُدٰى ۗ وَلَىِٕنِ اتَّبَعْتَ اَهْوَاۤءَهُمْ بَعْدَ الَّذِيْ جَاۤءَكَ مِنَ الْعِلْمِ ۙ مَا لَكَ مِنَ اللّٰهِ مِنْ وَّلِيٍّ وَّلَا نَصِيْرٍ ( البقرة: ١٢٠ )
Wa lan tardaa 'ankal Yahoodu wa lan Nasaaraa hattaa tattabi'a millatahum; qul inna hudal laahi huwalhudaa; wa la'init taba'ta ahwaaa'ahum ba'dal lazee jaaa'aka minal 'ilmimaa laka minal laahi minw waliyyinw wa laa naseer (al-Baq̈arah 2:120)
And never will the Jews and the Christians approve of you until you follow their religion. Say, "Indeed, the guidance of Allah is the [only] guidance." If you were to follow their desires after what has come to you of knowledge, you would have against Allah no protector or helper. (Al-Baqarah  : 120)

The Jews will never be pleased with you, nor will the Christians, unless you follow their faith. Say: “Guidance of Allah is, indeed, the guidance.” Were you to follow their desires despite the knowledge that has come to you, there shall be no friend for you against Allah, nor a helper.
