Surah Al-Baqara, Verse 101
وَلَمَّا جَآءَهُمْ رَسُولٌۭ مِّنْ عِندِ ٱللَّهِ مُصَدِّقٌۭ لِّمَا مَعَهُمْ نَبَذَ فَرِيقٌۭ مِّنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ كِتَٰبَ ٱللَّهِ وَرَآءَ ظُهُورِهِمْ كَأَنَّهُمْ لَا يَعْلَمُونَ
Translation — Sahih International
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].
