Al Baqarah Ayah 145

وَلَئِنْ أَتَيْتَ ٱلَّذِينَ أُوتُواْ ٱلْكِتَـٰبَ بِكُلِّ ءَايَةٍ مَّا تَبِعُواْ قِبْلَتَكَ‌ۚ وَمَآ أَنتَ بِتَابِعٍ قِبْلَتَهُمْ‌ۚ وَمَا بَعْضُهُم بِتَابِعٍ قِبْلَةَ بَعْضٍ‌ۚ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم مِّنۢ بَعْدِ مَا جَآءَكَ مِنَ ٱلْعِلْمِ‌ۙ إِنَّكَ إِذًا لَّمِنَ ٱلظَّـٰلِمِينَ ١٤٥ Even if you were to bring every proof to the People of the Book, they would not accept your direction ?of prayer?, nor would you accept theirs; nor would any of them accept the direction ?of prayer? of another. And if you were to follow their desires after ?all? the knowledge that has come to you, then you would certainly be one of the wrongdoers.
