Al Baqarah Ayah 146
ٱلَّذِينَ ءَاتَيْنَـٰهُمُ ٱلْكِتَـٰبَ يَعْرِفُونَهُۥ كَمَا يَعْرِفُونَ أَبْنَآءَهُمْۖ وَإِنَّ فَرِيقًا مِّنْهُمْ لَيَكْتُمُونَ ٱلْحَقَّ وَهُمْ يَعْلَمُونَ ١٤٦
Those We have given the Scripture recognize this ?Prophet? as they recognize their own children. Yet a group of them hides the truth knowingly.
