It is you who REFUSE to understand. I have given a very simple explanation. The fact is that you do not understand the intricacies of the Quranic system. To read the Quran from one angle is not appropiate. You interprete the Quran to your liking in order to deceive. What can we expect from a Bani Isreal, your forefathers have been doing that. Blood is much thicker then water. Seems to me that you smart alex bani Isreal, explain to me those verses.
Enough of this back and forth. This is not a joke, it is a serious matter, it relates to what God has or has not revealed. If you claim that those books called the Torah and Injeel today, are in fact corruptions/fabrications, then the burden is on you to explain the relevant Quranic verses. For your benefit, since you seem not to trust my own translations, I have posted below the verses in question, from three "reliable Muslim" translators.
Further, I will help you out with 541-43 The messenger is here told not to grive over hypocrites who eagerly devour evil and falsehood, even among the Jews. That he may judge equitably between them, if they come to him; however, he has no obligation to do so. Then the messenger is asked rhetorically Why should the Jews come to him when they have the Torah wherein is God's judgment? Yet they are turning away from it and therefore are not believers.
From these 3 verses alone it should be obvious that 1) At the time of the Quranic revelation, the Jews were in posession of a divine revelation, which God calls "Taurat" and 2) That the messenger's revelation (the Quran) did not in anyway supercede it. If it were not so, then the Jews definitely should have come to the messenger for judgment, which would make 543 meaningless and self contradictory.
I'll let you take it from here. Please remember to provide an explanation of each verse that is consistent with your belief that the Torah and Injeel, existing at the time of the Quranic revelation, were "fabrications". Also remember, it is irrelevant what you may think Torah and Injeel "really" mean, for you must interpret your definition, whatever it may be, consistently with the verses below.

YUSUFALI O Messenger! let not those grieve thee, who race each other into unbelief (whether it be) among those who say "We believe" with their lips but whose hearts have no faith; or it be among the Jews,- men who will listen to any lie,- will listen even to others who have never so much as come to thee. They change the words from their (right) times and places they say, "If ye are given this, take it, but if not, beware!" If any one's trial is intended by Allah, thou hast no authority in the least for him against Allah. For such - it is not Allah's will to purify their hearts. For them there is disgrace in this world, and in the Hereafter a heavy punishment.
PICKTHAL O Messenger! Let not them grieve thee who vie one with another in the race to disbelief, of such as say with their mouths "We believe," but their hearts believe not, and of the Jews listeners for the sake of falsehood, listeners on behalf of other folk who come not unto thee, changing words from their context and saying If this be given unto you, receive it, but if this be not given unto you, then beware! He whom Allah doometh unto sin, thou (by thine efforts) wilt avail him naught against Allah. Those are they for whom the Will of Allah is that He cleanse not their hearts. Theirs in the world will be ignominy, and in the Hereafter an awful doom;
SHAKIR O Messenger! let not those grieve you who strive together in hastening to unbelief from among those who say with their mouths We believe, and their hearts do not believe, and from among those who are Jews; they are listeners for the sake of a lie, listeners for another people who have not come to you; they alter the words from their places, saying If you are given this, take it, and if you are not given this, be cautious; and as for him whose temptation Allah desires, you cannot control anything for him with Allah. Those are they for whom Allah does not desire that He should purify their hearts; they shall have disgrace in this world, and they shall have a grievous chastisement in the hereafter.

YUSUFALI (They are fond of) listening to falsehood, of devouring anything forbidden. If they do come to thee, either judge between them, or decline to interfere. If thou decline, they cannot hurt thee in the least. If thou judge, judge in equity between them. For Allah loveth those who judge in equity.
PICKTHAL Listeners for the sake of falsehood! Greedy for illicit gain! If then they have recourse unto thee (Muhammad) judge between them or disclaim jurisdiction. If thou disclaimest jurisdiction, then they cannot harm thee at all. But if thou judgest, judge between them with equity. Lo! Allah loveth the equitable.
SHAKIR (They are) listeners of a lie, devourers of what is forbidden; therefore if they come to you, judge between them or turn aside from them, and if you turn aside from them, they shall not harm you in any way; and if you judge, judge between them with equity; surely Allah loves those who judge equitably.
005.043
YUSUFALI But why do they come to thee for decision, when they have (their own) law before them?- therein is the (plain) command of Allah; yet even after that, they would turn away. For they are not (really) People of Faith.
PICKTHAL How come they unto thee for judgment when they have the Torah, wherein Allah hath delivered judgment (for them)? Yet even after that they turn away. Such (folk) are not believers.
SHAKIR And how do they make you a judge and they have the Taurat wherein is Allah's judgment? Yet they turn back after that, and these are not the believers.
005.044
YUSUFALI It was We who revealed the law (to Moses) therein was guidance and light. By its standard have been judged the Jews, by the prophets who bowed (as in Islam) to Allah's will, by the rabbis and the doctors of law for to them was entrusted the protection of Allah's book, and they were witnesses thereto therefore fear not men, but fear me, and sell not my signs for a miserable price. If any do fail to judge by (the light of) what Allah hath revealed, they are (no better than) Unbelievers.
PICKTHAL Lo! We did reveal the Torah, wherein is guidance and a light, by which the prophets who surrendered (unto Allah) judged the Jews, and the rabbis and the priests (judged) by such of Allah's Scripture as they were bidden to observe, and thereunto were they witnesses. So fear not mankind, but fear Me. And barter not My revelations for a little gain. Whoso judgeth not by that which Allah hath revealed such are disbelievers.
SHAKIR Surely We revealed the Taurat in which was guidance and light; with it the prophets who submitted themselves (to Allah) judged (matters) for those who were Jews, and the masters of Divine knowledge and the doctors, because they were required to guard (part) of the Book of Allah, and they were witnesses thereof; therefore fear not the people and fear Me, and do not take a small price for My communications; and whoever did not judge by what Allah revealed, those are they that are the unbelievers.

YUSUFALI We ordained therein for them "Life for life, eye for eye, nose or nose, ear for ear, tooth for tooth, and wounds equal for equal." But if any one remits the retaliation by way of charity, it is an act of atonement for himself. And if any fail to judge by (the light of) what Allah hath revealed, they are (No better than) wrong-doers.
PICKTHAL And We prescribed for them therein The life for the life, and the eye for the eye, and the nose for the nose, and the ear for the ear, and the tooth for the tooth, and for wounds retaliation. But whoso forgoeth it (in the way of charity) it shall be expiation for him. Whoso judgeth not by that which Allah hath revealed such are wrong-doers.
SHAKIR And We prescribed to them in it that life is for life, and eye for eye, and nose for nose, and ear for ear, and tooth for tooth, and (that there is) reprisal in wounds; but he who foregoes it, it shall be an expiation for him; and whoever did not judge by what Allah revealed, those are they that are the unjust.
005.046
YUSUFALI And in their footsteps We sent Jesus the son of Mary, confirming the Law that had come before him We sent him the Gospel therein was guidance and light, and confirmation of the Law that had come before him a guidance and an admonition to those who fear Allah.
PICKTHAL And We caused Jesus, son of Mary, to follow in their footsteps, confirming that which was (revealed) before him in the Torah, and We bestowed on him the Gospel wherein is guidance and a light, confirming that which was (revealed) before it in the Torah - a guidance and an admonition unto those who ward off (evil).
SHAKIR And We sent after them in their footsteps Isa, son of Marium, verifying what was before him of the Taurat and We gave him the Injeel in which was guidance and light, and verifying what was before it of Taurat and a guidance and an admonition for those who guard (against evil).
005.047
YUSUFALI Let the people of the Gospel judge by what Allah hath revealed therein. If any do fail to judge by (the light of) what Allah hath revealed, they are (no better than) those who rebel.
PICKTHAL Let the People of the Gospel judge by that which Allah hath revealed therein. Whoso judgeth not by that which Allah hath revealed such are evil-livers.
SHAKIR And the followers of the Injeel should have judged by what Allah revealed in it; and whoever did not judge by what Allah revealed, those are they that are the transgressors.
005.048
YUSUFALI To thee We sent the Scripture in truth, confirming the scripture that came before it, and guarding it in safety so judge between them by what Allah hath revealed, and follow not their vain desires, diverging from the Truth that hath come to thee. To each among you have we prescribed a law and an open way. If Allah had so willed, He would have made you a single people, but (His plan is) to test you in what He hath given you so strive as in a race in all virtues. The goal of you all is to Allah; it is He that will show you the truth of the matters in which ye dispute;
PICKTHAL And unto thee have We revealed the Scripture with the truth, confirming whatever Scripture was before it, and a watcher over it. So judge between them by that which Allah hath revealed, and follow not their desires away from the truth which hath come unto thee. For each We have appointed a divine law and a traced-out way. Had Allah willed He could have made you one community. But that He may try you by that which He hath given you (He hath made you as ye are). So vie one with another in good works. Unto Allah ye will all return, and He will then inform you of that wherein ye differ.
SHAKIR And We have revealed to you the Book with the truth, verifying what is before it of the Book and a guardian over it, therefore judge between them by what Allah has revealed, and do not follow their low desires (to turn away) from the truth that has come to you; for every one of you did We appoint a law and a way, and if Allah had pleased He would have made you (all) a single people, but that He might try you in what He gave you, therefore strive with one another to hasten to virtuous deeds; to Allah is your return, of all (of you), so He will let you know that in which you differed;
005.049
YUSUFALI And this (He commands) Judge thou between them by what Allah hath revealed, and follow not their vain desires, but beware of them lest they beguile thee from any of that (teaching) which Allah hath sent down to thee. And if they turn away, be assured that for some of their crime it is Allah's purpose to punish them. And truly most men are rebellious.
PICKTHAL So judge between them by that which Allah hath revealed, and follow not their desires, but beware of them lest they seduce thee from some part of that which Allah hath revealed unto thee. And if they turn away, then know that Allah's Will is to smite them for some sin of theirs. Lo! many of mankind are evil-livers.
SHAKIR And that you should judge between them by what Allah has revealed, and do not follow their low desires, and be cautious of them, lest they seduce you from part of what Allah has revealed to you; but if they turn back, then know that Allah desires to afflict them on account of some of their faults; and most surely many of the people are transgressors.
