اَلَّذِيْنَ اٰتَيْنٰهُمُ الْكِتٰبَ يَعْرِفُوْنَهٗ كَمَا يَعْرِفُوْنَ اَبْنَاۤءَهُمْ ۗ وَاِنَّ فَرِيْقًا مِّنْهُمْ لَيَكْتُمُوْنَ الْحَقَّ وَهُمْ يَعْلَمُوْنَ ( البقرة: ١٤٦ )
Allazeena aatainaahumul kitaaba ya'rifoonahoo kamaa ya'rifoona abnaaa'ahum wa inna fareeqam minhum layaktumoonal haqqa wa hum ya'lamoon (al-Baq̈arah 2:146)
Those to whom We gave the Scripture know him [i.e., Prophet Muhammad (^)] as they know their own sons. But indeed, a party of them conceal the truth while they know [it]. (Al-Baqarah  : 146)
1 Mufti Taqi Usmani
Those whom We have given the Book recognize him (the Holy Prophet) as they recognize their own sons. In fact, a group of them conceals the truth, while they know (it).
