Surah Al-Baqarah, Verse 146

ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمۡۖ وَإِنَّ فَرِيقٗا مِّنۡهُمۡ لَيَكۡتُمُونَ ٱلۡحَقَّ وَهُمۡ يَعۡلَمُونَ١٤٦

alladhīna ātaynāhumu l-kitāba yaʿrifūnahu kamā yaʿrifūna abnāahum wa-inna farīqan min'hum layaktumūna l-ḥaqa wahum yaʿlamūna

Those to whom We gave the Scripture know him [i.e., Prophet Muḥammad (ﷺ)] as they know their own sons. But indeed, a party of them conceal the truth while they know [it].
