There is a huge trend among non Muslims who are eager to spread false information for their own interest claiming that Muhammad prayer and peace be upon him authored the Quran, copied from Christian scriptures..etc.
The following set of Ayahs had been revealed in specific situation, that will be explained later In sh a Allah:
"
Quran.nu (if you visit the site, use the translation of Quran.nu, as an Arabic speaker Alhamdulelah, it is the best among other translations I mean closest to the Arabic meaning). Will discuss this point in another message In sh a Allah.
"Surely, We have sent down to
you
the Book
<span style="color:rgb(68,68,68);"> in truth that you might judge between men by that which Allah has shown you
<span style="color:rgb(68,68,68);">, so be not a pleader for the treacherous.*And seek the Forgiveness of Allah, certainly, Allah is Ever Oft Forgiving, Most Merciful.*And argue not on behalf of those who deceive themselves. Verily, Allah does not like anyone who is a betrayer of his trust, and indulges in crime.*They may hide (their crimes) from men, but they cannot hide (them) from Allah, for He is with them (by His Knowledge), when they plot by night in words that He does not approve, And Allah ever encompasses what they do.*Lo! You are those who have argued for them in the life of this world, but who will argue for them on the Day of Resurrection against Allah, or who will then be their defender?* And whoever does evil or wrongs himself but afterwards seeks Allah's Forgiveness, he will find Allah Oft Forgiving, Most Merciful.* And whoever earns sin, he earns it only against himself. And Allah is Ever All Knowing, All Wise."
And whoever earns a fault or a sin and then throws it on to someone innocent, he has indeed burdened himself with falsehood and a manifest sin." (Quran 4: 105-112)

The situation of revealing the aforementioned set of Ayahs is as follows:
A Muslim man from Bani Ubayraq Ibn Zafar Ibnel Hareth (bani means children of) from the Ansar (the supporters who received the Messenger salla Allah a`lyhee wa sallam when he came to Medina, opened their houses for the immigrants, shared their wealth..etc with them so they have a very special position in the eyes of Allah) his name as reported was Te`ma Ibn Ubayreq, he stole an armor from his Muslim neighbour named as Qatada Ibn Alno`man, the armor was placed in in a flour sack, due to a hole in the sack, the flour sprinkled while he was going home, but instead he kept it in hiding in the house of a Jew called (Zayd Bin Alsameen). People started searching for the armor at Ta`eman's house, but he took an oath in the name of Allah that he did not take it. The armor's owners said: we observed the traces of flour inside his house, but as he took the oath, they left him and traced the flour till it took them to the house of the Jew where they found the armor. The Jew man said Ta`ema Ibn Ubayreq put it here!!. The relatives of Ta`ema went to the Messenger of Allah salla Allah a`lyhee wa sallam and requested that he argues in favour of their relative, Rasullah was about to punish the Jew, when Allah revealed the above mentioned set of Ayahs showing the innocence of the Jewish man. As you can see the Messenger salla Allah a`lyhee wa sallam, in his capacity as judge in this situation, based on evidences and inferences thought that the Jewish man is the thief, but Allah Does not Accept unjust, even if the innocent person someone who does not believe in Islam, part of a community that is constantly plotting against the Messenger salla Allah a`lyhee wa sallam, working hard to harm the Muslim community and destroy Islam all together including attempts against the life of the Messenger salla Allah a`lyhee wa sallam.
This shows that Allah truly revealed this Quran, otherwise, if the Messenger salla Allah a`lyhee wa sallam was the author, how did he learn about the real perpetrator, and how courageous was he to say it out loud and uncover the innocence of the Jewish man, unless these are divine orders that he has to convey and not break or violate.
This situation has other aspects to discuss, but in a separate post In sh a Allah.
