Quran 2:145 from Surah Al-Baqara on Divine Marvels.
وَلَئِنۡ أَتَيۡتَ ٱلَّذِينَ أُوتُواْ ٱلۡكِتَٰبَ بِكُلِّ ءَايَةٖ مَّا تَبِعُواْ قِبۡلَتَكَۚ وَمَآ أَنتَ بِتَابِعٖ قِبۡلَتَهُمۡۚ وَمَا بَعۡضُهُم بِتَابِعٖ قِبۡلَةَ بَعۡضٖۚ وَلَئِنِ ٱتَّبَعۡتَ أَهۡوَآءَهُم مِّنۢ بَعۡدِ مَا جَآءَكَ مِنَ ٱلۡعِلۡمِ إِنَّكَ إِذٗا لَّمِنَ ٱلظَّٰلِمِينَ
English translation: And even if you come (to) those who were given the Book with all (the) signs not they would follow your direction of prayer and not (will) you (be) a follower (of) their direction of prayer And not some of them (are) followers (of the) direction of prayer (of each) other And if you followed their desires from after [what] came to you of the knowledge indeed, you (would) then (be) surely among the wrongdoers
