Summary:

  
(a)-  The Quran has no crookedness عوج 3:99, 18:1, 39:28.    These Noble Verses clearly imply that only the Quran is without crookedness, since according to the Quran, what disagrees with the Quran is false, and the Quran was sent by Allah Almighty to show the people of the Book their falsehoods and conjectures:

On Bibles' Conjectures:

1-  The Bibles, Apocryphas and Talmuds are filled with conjecture:

[051:008] Truly ye are in a doctrine discordant (i.e., disagreeing)

2-  The Quran came to show the people of the Book some of the corruptions in their writings:

a.  Again, Noble Verses 4:157, 2:78, 4:157, 16:64, 10:36, 10:66, 53:28 about the NT and apocryphas being full of conjectures.  Also:

b.  [016:064] And We sent down the Book to thee (Muhammad) for the express purpose, that thou shouldst make clear to them those things in which they differ, and that it should be a guide and a mercy to those who believe.

c.  [027:076] Verily this Quran relates يقص to the Children of Israel most of the matters in which they disagree.

d.  [051:008] Truly ye are in a doctrine discordant (i.e., disagreeing)

e.  Only the Quran's Revelation is pure.  Never did Allah Almighty say this about any other book: [098:002] A Messenger from ALLAH, reciting unto them the pure Scriptures,

The purity here is not the actual man-made paper pages.  It is the Holy and Pure Words of the Glorious Quran.  Quran is made of perfect Scrolls كتب قيمة , and Islam is the perfect religion دين القيمة from GOD 98:1-7.

(c)-  Noble Verses 5:44-49 in details:

Quran is the Grand Judgment:

(d)-  The Jews and Christians are in disputes and differences over their texts: 2:113, 2:176, 2:213, 2:253, 3:19, 3:55, 3:105, 4:157, 5:48, 6:141, 6:164, 8:42, 10:19, 10:93, 11:110, 16:39, 16:64, 10:36, 10:66, 53:28, 16:69, 16:92, 16:124, 27:76, 39:3, 41:45, 42:10, 43:63, 45:17, 51:8, 78:3.

(e)-  The Quran shows the people of the Book some of where they're wrong 16:64, 10:36, 10:66, 53:28:

[051:008] Truly ye are in a doctrine discordant (i.e., disagreeing)

[016:064]  And We sent down the Book to thee for the express purpose, that thou shouldst make clear to them those things in which they differ, and that it should be a guide and a mercy to those who believe.

The Quran correcting the Bibles' (plural) accounts:

1.  200+ Ways the Quran Corrects the Bibles: html, pdf.
2.  GOD has no Divine son.
3.  Jesus never got crucified nor killed.
4.  Jesus' real name was Isa (eesa).
5.  Trinity is a lie.
6.  Sinful made lawful.  The blasphemous and man-made lie that is called "Christianity" turned many sinful things into lawful, and lawful into sinful.
  

(f)-  The people of the Book are in constant doubt regarding their Book 11:110, 41:45:

[011:110]  We certainly gave the Book to Moses, but differences arose therein: had it not been that a word had gone forth before from thy Lord, the matter would have been decided between them, but they are in suspicious doubt concerning it.

[041:045]  We certainly gave Moses the Book aforetime: but disputes arose therein. Had it not been for a Word that went forth before from thy Lord, (their differences) would have been settled between them: but they remained in suspicious disquieting doubt thereon.

[051:008] Truly ye are in a doctrine discordant (i.e., disagreeing)
  

(g)-  The Quran's text is GOD's chosen text 39:23:

See also 2:2, 2:151, 2:176-177, 3:164, 4:105, 4:113, 6:114, 6:155, 10:1, 10:37, 11:1, 12:1, 13:1, 13:43, 14:1, 15:1, 18:1, 26:2, 27:1, 28:2, 31:2, 32:2, 35:31, 39:23, 40:2, 41:3, 41:41, 43:2, 52:2, 56:78.

(h)-  The Quran's scrolls are purified صحفا مطهرة , are of great value, and contain solid proofs for the Jews, Christians and the infidels that the Quran is made of perfect Scrolls كتب قيمة , and Islam is the perfect religion دين القيمة from GOD 98:1-7.

(i)-  The Quran came to confirm the Truth in the Jews' writings that were "between his hands": 2:41, 2:91, 2:97, 3:3, 4:47, 5:48, 35:51, 46:30.

(j)-  The Quran came to change some of the Jewish Laws 3:50.

(k)-  The Jews' and Christians' books are full of crookedness عوج, and they tried very hard to also make the Quran crooked (3:99, 7:45, 7:86, 11:19, 14:3, 16:124, 18:1, 39:28).

(l)-  Allah Almighty allowed for all other Books to get corrupt and even get permanently lost.  The following are some examples:

      Books of Ishmael:

[034:044]  Although, prior to you We did not give them (the pagan Arabs) a book they could study, nor did We send a warner towards them.

But they had Prophets Ishmael and Abraham sent to them before with Books:

[002:127]  And remember the time when Abraham and Ishmael raised the foundations of the house (Kaaba in Meca), praying, `Our Lord, accept this from us; for thou art the All-Hearing, the All-Knowing;

[002:136]  Say (O Muslims  (Isaiah 56:5: the future believers' name.  Sons and daughters titles will be "no more")): We believe in Allah and that which is revealed unto us and that which was revealed unto Abraham, and Ishmael, and Isaac, and Jacob, and the tribes, and that which Moses and Jesus received, and that which the prophets received from their Lord. We make no distinction between any of them, and unto Him we have surrendered.

Where are Ishmael's Divine Revelations?  We simply do not have them.

     Books of many Prophets:

[002:213]  Mankind was one single nation, and God sent Messengers with glad tidings and warnings; and with them He sent the Book in truth, to judge between people in matters wherein they differed; but the People of the Book, after the clear Signs came to them, did not differ among themselves, except through selfish contumacy. God by His Grace Guided the believers to the Truth, concerning that wherein they differed. For God guided whom He will to a path that is straight.

The overwhelming majority of their accounts are permanently lost.  We have no idea what their contents were.

(m)-  The Glorious Quran thoroughly corrects the Bibles' (plural) accounts and errors:

(n)-  The Jews and Christians write false books and call them Apocryphas, Talmuds and Bibles:

[051:008] Truly ye are in a doctrine discordant (i.e., disagreeing)

General Principle:

The following Noble Verse 2:79 is a general principle and not limited to people in the Prophet's time:

[002:079]  Then woe to those who write the Book with their own hands, and then say: "This is from God," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby.

1.  The general principle here is similar to the "Produce your Proof if you are Truthful" one in 2:111.  It is not just limited to the people of the Book.  It is for Muslims  (Isaiah 56:5: the future believers' name.  Sons and daughters titles will be "no more") and for all people.

2.  Another general principle example is the freeing of all slaves Quranic Law.

Slavery Example:

Another example of the Glorious Quran's general principle VS. local and limited situations (i.e., in the interim of things), is the law of slavery.  Allah Almighty's Highest Standard regarding slavery is to end it in all of the lands:

[090:012] And what will make you comprehend what the uphill road is?
[090:013] (It is) the setting free of a slave,

So one of the monumental tasks upon the Muslims  (Isaiah 56:5: the future believers' name.  Sons and daughters titles will be "no more") is to end all forms of slavery.  Yet, the Glorious Quran also allows enslaving, buying slaves, selling slaves, having harems (female slaves).  So is this a contradiction?  No.  Is this an abrogation (90:12-13 abrogating all other verses or vise versa)?  No.  All Noble Verses concerning slaves and slavery still stand TILL THIS DAY!  All 6236 Noble Verses that make up the entire Glorious Quran still stand today and will always stand till the Day of Judgment.  We have no abrogation here.  The Muslim State and Court and people must be mindful that Allah Almighty has set high and monumental goals in the Glorious Quran.  In the interim of things, however, the slavery Noble Verses could be activated and applied due to battles that may occur or deals and/or transactions.  But the ultimate goal must be to end all forms of slavery in all Muslim lands.

[051:008] Truly ye are in a doctrine discordant (i.e., disagreeing)

[004:046]  Some of those who are Jews change words from their context and say: "We hear and disobey; hear thou as one who heareth not" and "Listen to us!" distorting with their tongues and slandering religion. If they had said: "We hear and we obey: hear thou, and look at us" it had been better for them, and more upright. But Allah hath cursed them for their disbelief, so they believe not, save a few.

[005:041]  O Apostle! 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 God, thou hast no authority in the least for him against God. For such - it is not God's will to purify their hearts. For them there is disgrace in this world, and in the Hereafter a heavy punishment.

Indeed they did and still do and will always do.  Proven with images, text and videos from their corrupt bible and books.  They remove words and alter words.  Also visit:

The Glorious Quran is also in perfect agreement with this:

[002:087] We gave Moses the Book and followed him up with a succession of apostles....
[017:002] We gave Moses the Book, and made it a Guide to the Children of Israel, (commanding)....
[025:035] (Before this,) We sent Moses The Book, and appointed his brother Aaron with him as minister;
