And every time i made a good point she came back with the statement "The Bible was made by Man so therefore not from God
Very early Islamic sources had some interesting things to say abut the origin of the Quran [ Ibn Ishaq died in 761, and wrote the first biography on Muhammad]-
‘A more ancient historian, Wakidi, has the following sentence in which it is suggested that ‘Abdallah b. Sa’d b. Abi Sarh, and a Christian slave, ibn Qumta, had something to do with the Koran. And ibn Abi Sarh came back and said to Quraish: “It was only a Christian slave who was teaching him (Muhammad); I used to write to him and change whatever I wanted.”’.....
Please note that Abdallah b. Sa’d b Abi Sarh was Muhammad’s trusted scribe. When Muhammad migrated to Medina Abdallah also followed him. Whenever Muhammad went into a trance he would dictate Abdallah to write down his utterances. When Abdallah suggested some changes to Muhammad’s lisping, Muhammad would readily agree with Abdallah.... This led Abdallah to suspect Muhammad’s claim of reception of messages from Allah, apostatised and left Medina for Mecca. He then proclaimed that he (Abdallah) too could easily write the Qur’anic verses being inspired by Allah...Muhammad was furious and sought Allah’s help. Allah promptly sent down verse 6:93, condemning any one who claims to be inspired by Allah....When Muhammad occupied Mecca he earmarked 8 [or10 (6 men, 4 women) according to Ibn Sa’d, vol. ii, p165] people to be killed even if they were found in the precinct of Ka’ba. Abdallah was one of them.
A Christian who converted to Islam wrote Muhammad's revelations; then he reverted back to Christianity and claimed that Muhammad knew nothing and he wrote the Quran for Muhammad; when this man died his body was repeatedly thrown out from the grave...4.56.814
Volume 4, Book 56, Number 814:
Narrated Anas:
There was a Christian who embraced Islam and read Surat-al-Baqara and Al-Imran, and he used to write (the revelations) for the Prophet. Later on he returned to Christianity again and he used to say: "Muhammad knows nothing but what I have written for him." ....
We need to mention here two other main contributors to the Qur’an. They were Abdullah b. Salam and Mukhayariq. According to Ibn Ishaq (Ibn Ishaq, p.239) Abdullah b. Salam b. al-Harith was a Jew from B. Qaynuqa who converted to Islam when Muhammad arrived at Medina. Mukhayariq, too, was a Jewish Rabbi from B. Thalaba and he also converted to Islam. Abdullah b. Salam was an authority on Torah, and had undoubtedly contributed to write in the Qur’an, the Jewish stuff--especially the Jewish laws.
Here is a brief list of some of the materials in the Qur’an that Muhammad copied/adopted from the Christians, the Jews, the Armenians, the Hindus and the Magians (Zoroastrians):
Tayammum (4:43): Copied from the Jewish Scripture the Talmud.

Angel of death--Azrail or Azazil, Malaku’l Maut (6:61, 7:37, 32:11): Adopted from the Jewish and the Magian (Zoroastrian) scriptures....
Muhammad’s neighbour was an-Nadr b. al-Harith. He also used to write verses similar to the Qur’an. He was also a very good story-teller--especially of the ancient fables. Whenever Muhammad gathered people to listen to his tales in the Qur’an an-Nadr would entice the audience of Muhammad with better stories than Muhammad. Due to an-Nadr’s excellent proficiency in narrating the anecdotes Muhammad saw his audience disappear. Muhammad considered an-Nadr’s act extremely loathsome and had his revenge taken by capturing an-Nadr in the battle of Badr and later beheading him.
