Surah Al-Baqarah (The Cow), Verse 146

اَلَّذِیْنَ اٰتَیْنٰهُمُ الْكِتٰبَ یَعْرِفُوْنَهٗ كَمَا یَعْرِفُوْنَ اَبْنَآءَهُمْ وَاِنَّ فَرِیْقًا مِّنْهُمْ لَیَكْتُمُوْنَ الْحَقَّ وَهُمْ یَعْلَمُوْنَ ۟

Allazeena aatainaahumul kitaaba ya'rifoonahoo kamaa ya'rifoona abnaaa'ahum wa inna fareeqam minhum layaktumoonal haqqa wa hum ya'lamoon

“The people of the Book know this as they know their own sons; but some of them conceal the truth which they themselves know.”
