(6:91) And they did not appraise Allah with true appraisal when they said, “Allah did not reveal to a human being anything.” Say, “Who revealed the Scripture that Moses brought as light and guidance to the people? You [Jews] make it into pages, disclosing [some of] it and concealing much. And you were taught that which you knew not – neither you nor your fathers.” Say, “Allah [revealed it].” Then leave them in their [empty] discourse, amusing themselves.
Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan,
(6:91) They (the Jews, Quraish pagans, idolaters, etc.) did not estimate Allah with an estimation due to Him when they said: “Nothing did Allah send down to any human being (by inspiration).” Say (O Muhammad SAW): “Who then sent down the Book which Musa (Moses) brought, a light and a guidance to mankind which you (the Jews) have made into (separate) papersheets, disclosing (some of it) and concealing (much). And you (believers in Allah and His Messenger Muhammad SAW), were taught (through the Quran) that which neither you nor your fathers knew.” Say: “Allah (sent it down).” Then leave them to play in their vain discussions. (Tafsir Al-Qurtubi, Vol. 7, Page 37).
Mohammed Marmaduke William Pickthall
(6:91) And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling.
Abdullah Yusuf Ali
(6:91) No just estimate of Allah do they make when they say: “Nothing doth Allah send down to man (by way of revelation)” Say: “Who then sent down the Book which Moses brought?- a light and guidance to man: But ye make it into (separate) sheets for show, while ye conceal much (of its contents): therein were ye taught that which ye knew not- neither ye nor your fathers.” Say: “Allah (sent it down)”: Then leave them to plunge in vain discourse and trifling.
Mohammad Habib Shakir
(6:91) And they do not assign to Allah the attributes due to Him when they say: Allah has not revealed anything to a mortal. Say: Who revealed the Book which Musa brought, a light and a guidance to men, which you make into scattered writings which you show while you conceal much? And you were taught what you did not know, (neither) you nor your fathers. Say: Allah then leave them sporting in their vain discourses.
Dr. Ghali
(6:91) And in no way have they estimated Allah His true estimate as they said, “In no way has Allah sent down anything on any mortal.” Say, “Who sent down the Book that Musa (Moses) came with (as) a light and a guidance to mankind? You make it into papers, displaying them, and concealing much; and you were taught what you did not know yourselves, nor your fathers.” Say, ” Allah.” Thereafter leave them out, playing in their wading (i.e; plunge in vain discourse).
Ali Unal
(6:91) And they (some of the Jews) had no true judgment of God as His right (in being God requires), when they say: “God has not sent anything down on any human being.” Say: “Then, who sent down the Book which Moses brought as a light, and guidance for the people (you know), and which you put into, and treat as, mere leaves of paper to make show of, while you conceal much of it, and you have been taught (by it) what neither you knew nor your forefathers?” Say: “God (sent it down),” and then leave them to their game of plunging into vanities.

(6:91) And they did not evaluate God His correct/just value/estimation, when they said: “God did not descend on (a) human from a thing.” Say: “Who descended The Book which Moses came with it, (as) a light and guidance to the people? You make it papers/parchments, you show it and you hide much, and you were taught/instructed what you did not know, you and nor your fathers/forefathers.” Say: “God.” Then leave them in their plunging, they play/amuse/enjoy/joke/mock.
Ahmed Ali
(6:91) But they failed to make a just estimation of God when they said: “He did not reveal to any man any thing.” Ask them: “Who then revealed the Book that Moses brought, — a guidance and light for men, — which you treat as sheafs of paper, which you display, yet conceal a great deal, though through it you were taught things you did not know before, nor even your fathers knew?” Say: “God,” and leave them to the sport of engaging in vain discourse.

And ye were taught that which ye knew not: neither ye nor your fathers. Say thou: Allah, and let them alone, sporting in their vain discourse.
Maulana Mohammad Ali
(6:91)-
Muhammad Sarwar
(6:91) They have no true respect of God when they say, “God has not sent anything to a mortal being.” (Muhammad), tell them, “Who revealed the Book containing a light and guidance for the people which Moses brought? You wrote down only some parts of the original on paper and hid much, even after having learnt from it, that which neither you nor your fathers knew.” Tell them, “God has (revealed the Quran),” and then leave them alone to pursue their useless investigations.
