Al-Baqarah - 2:120

وَلَن تَرْضَى عَنكَ الْيَهُودُ وَلاَ النَّصَارَى حَتَّى تَتَّبِعَ مِلَّتَهُمْ قُلْ إِنَّ هُدَى اللّهِ هُوَ الْهُدَى وَلَئِنِ اتَّبَعْتَ أَهْوَاءهُم بَعْدَ الَّذِي جَاءكَ مِنَ الْعِلْمِ مَا لَكَ مِنَ اللّهِ مِن وَلِيٍّ وَلاَ نَصِيرٍ
[2:120]
And the Jews will not be pleased with you, nor the Christians until you follow their religion. Say: Surely Allah's guidance, that is the (true) guidance. And if you follow their desires after the knowledge that has come to you, you shall have no guardian from Allah, nor any helper.
Never will the Jews or the Christians be satisfied with thee unless thou follow their form of religion. Say: "The Guidance of Allah,-that is the (only) Guidance." Wert thou to follow their desires after the knowledge which hath reached thee, then wouldst thou find neither Protector nor helper against Allah.
And the Jews will not be pleased with thee, nor will the Christians, till thou follow their creed. Say: Lo! the guidance of Allah (Himself) is Guidance. And if thou shouldst follow their desires after the knowledge which hath come unto thee, then wouldst thou have from Allah no protecting guardian nor helper.
