Quran 2:146 from Surah Al-Baqara on Divine Marvels.
ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمۡۖ وَإِنَّ فَرِيقٗا مِّنۡهُمۡ لَيَكۡتُمُونَ ٱلۡحَقَّ وَهُمۡ يَعۡلَمُونَ
English translation: (To) those whom We gave [them] the Book they recognize it like they recognize their sons And indeed a group of them surely they conceal the Truth while they know
Transliteration: alladhina ataynahumu al-kitaba ya'rifunahu kama ya'rifuna abnaahum wa-inna fariqan min'hum layaktumuna al-haqa wahum ya'lamuna
