[Asad]
6:18 Say: "What could most weightily bear witness to the truth?" Say: "God is witness between me and you; and this Qur?an has been revealed unto me so that on the strength thereof I might warn you and all whom it may reach." Could you in truth bear witness that there are other deities side by side with God? Say: "I bear no [such] witness!" Say: "He is the One God; and, behold, far be it from me to ascribe divinity, as, you do, to aught beside Him!"
6:19
[Asad]
They unto whom we have vouchsafed revelation aforetime know this as they know their own children; yet those [of them] who have squandered their own selves -it is they who refuse to believe.
Shakir:
Those whom We have given the Book recognize him as they recognize their sons; (as for) those who have lost their souls, they will not believe.
Shabbir:
Those who have been given the Scripture, recognize this fact as they recognize their sons (the fact of God's Transcendental Uniqueness and Oneness). Yet those who have squandered their own "Self" fail to accept such undeniable Truth.
[Al-Muntakhib]
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.
Question: What the Qur?an mean by ?They recognize as they recognize their sons??. Is (tying it to the previous verse) it the fact that Alalh is One and he has no partners? Or does it mean that the People of the Book recognize Muhammad (S) as a true Messenger? If the latter is meant than the question would arise as to why would they not accept him even though they recognize him as they would their sons?
The issue is the way Qur?an is translated. Although each translator tries to the best he/she can, sometimes the way they go about it, does not satisfy a curious mind.
