THE GUIDANCE OF ALLAH IS THE ONLY GUIDANCE. 

And never will the Jews or 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.

ولن ترضى عنك اليهود ولا النصارى حتى تتبع ملتهم ۗ قل إن هدى الله هو الهدى ۗ ولئن اتبعت أهواءهم بعد الذي جاءك من العلم ۙ ما لك من الله من ولي ولا نصير

[Quran 2:120]
