Those to whom We have given the Scripture recognize it as they (6:20)

Almuntakhab Fi Tafsir Alquran Alkarim

Those who were recipients of Our Word -Jews and Christians- to whom We gave the Book -AL-Tawrah and AL-Injil (Torah and Bible) do recognize this Book -the Quran- as well as the Messenger to whom it is sent. They assert the existence of this reality as much as they are able to assert the identity of their sons, but those who are cheaply vicious to the perdition of their own souls refuse to recognize the truth

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(6:20) Those whom We have given the Book will recognize this just as they recognize their own ofspring; *14 but those who have courted their own ruin will not believe.

Those to whom We have given the Scripture recognize it as they meaning

*14). Those who have knowledge of the Scriptures know for sure that God is One alone and that no one shares His godhead with Him. It is true that one can spot one's own child even in the midst of a large crowd of children. The same can be said about those well-versed in the Scriptures. Even if the true concept of godhead were interspersed among numerous false beliefs and concepts about God, those well-versed in the scriptural lore would be able to recognize without doubt which doctrine was true.

جن لوگوں کو ہم نے کتاب دی ہے وہ اس بات کو اس طرح غیر مشتبہ طور پر پہچانتے ہیں جیسے ان کو اپنے بیٹوں کے پہچاننے میں کوئی اشتباہ پیش نہیں آتا مگر جنہوں نے اپنے آپ کو خود خسارے میں ڈال دیا ہے وہ اِسے نہیں مانتے
