Qur'ān 2:101 · Al-Baqarah (البقرة)

وَلَمَّا جَآءَهُمْ رَسُولٌۭ مِّنْ عِندِ ٱللَّهِ مُصَدِّقٌۭ لِّمَا مَعَهُمْ نَبَذَ فَرِيقٌۭ مِّنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ كِتَـٰبَ ٱللَّهِ وَرَآءَ ظُهُورِهِمْ كَأَنَّهُمْ لَا يَعْلَمُونَ

And when a messenger from Allah came to them confirming that which was with them, a party of those who had been given the Scripture threw the Scripture of Allah behind their backs as if they did not know [what it contained].
