I think I found an answer after long searching
The correctness of the Bible according to the Ahadeeth
We have seen in the previous chapter, that there are about 100 verses
in the Quran concerning the Tourat and the Injeel. So it is not
strange that the Hadeeth has mention about them.
The Prophet (Peace and blessings be upon Him) said: There will be in
the end of time charlatan liars coming to you with narrations that you
nor your fathers heard, so beware of them lest they misguide you and
cause you tribulations. Muslim
Abu Huraira Said: The people of the Scripture (Jews) used to recite
the Torah in Hebrew and they used to explain it in Arabic to the
Muslims. On that Allah's Messenger (sallallahu 'alaihi wa sallam)
said, "Do not believe the people of the Scripture or disbelieve them,
but say:-- "We believe in Allah and what is revealed to us." (2.136)
It is clear that Muhammad did not support nor fight against the tafseer/explanation of the people of the book to their book, nor did He make any comments on the text. And the Muslimeen of the time did not know whether the explanation of the Jews on the Tourat, actually agrees with the text itself or is not in accordance with the text.
Abu Hurara narrated, that the Prophet said to Ubai bin Ka'b: how do
you read in salat? So He read Surat Al Fatihah/The Mother of the book
so the Messanger said: By the one who has my soul in His hands,
nothing came down in the Tourat, the Injeel, the Zaboor, nor the Quran
like it, and it is the Sab'ul Mathani and the Qur'anul Adheem that was
given to me.
Mishkah, Hadith 2142, Narrated by Attirmidhi
Narrated by Jaabir, that Ummar binul Khattab cam to the Prophet with a
copy of the Tourat and sid: O messenger this is a copy of the Tourat.
The Messenger remained silent. So ummar started to read while the
Prophet's face started to change. So Abu Bakr said: Your women have
lost you (unsure translation, original is: ثكلتك الثواكل) Do not
you see the change in expression of the face of the Prophet? So Ummat
looked and said: I seek refuge in Allah from His Anger and his
messenger's(anger). We have accepted Allah as our lord and Islam as
our way and Muhammad as our prophet. So the Prophet said: by the one
who has my soul in His hands, if you were to follow Musa/Moses and
leave me, you would lose your way, and if, and If Musa/Moses were to
be Alive in my time, He would follow me.
Misha't, Hadith 195, narrated by Addarmy
Narrated by Salman: I read in the Tawrah that the blessing for food is
in the Wudu' after it. So I mentioned that to the Prophet (sallallahu
'alaihi wa sallam), telling him what I read in the Tawrah. So the
Messenger of Allah (sallallahu 'alaihi wa sallam) said: 'The food's
blessing is in the Wudu' before it and the Wudu' after it.'"
Narrated by both Abu Dawood and Attirmidhy, the grade of the Hadith is weak.
here Muhammad does not forbid the reading of the Tourat nor does He refute their existence. And His silence is proof for their existence. Let us meditate on the following Hadith:
Narrated by Khaithama bin Abi Sbra: I came to Madinah and I asked Allah
for a righteous companion, so He pointed me to Aba Hurayra, so I sat
and told Him: i asked Allah to make it easy for me to find a righteous
companion فوُفّقتَ لي . H said to me, from where did you come from?
I said: From Koofah, I came looking got good and ask for it. So Abu
Hrairah said: Don't you have among you Sa'd bin Malik the one who's
Du'a is accepted? and Ibn Mas'ood صاحب طهور رسول الله ونعليه ? and
Hudhaifah the companion of the secret of the Prophet? And Ammar the
one Allah saved from the Shaitan on the tongue of the Prophet(وعمار
الذي أجاره الله من الشيطان على لسان نبيه)? And Salman the owner of the
two books (meaning the Injeel and the Quran).
Mishkat, Hadith 6424, Narrated by Attirmidhy
It is clear that the above Hadith makes known that the two books are the Injeel and the Quran, not the Tourat and the Injeel. And this makes certain that at the time of the early Muslims, there was a correct Injeel that they read.
Narrated by Ziad bin Lubaid: The Prophet recalled something and said:
That is the time when the knowledge goes. I asked: and how would the
knowledge go when we read the Quran and we teach it to our children
and our children read it until judgement day? The messenger replied:
Oh Ziad, Your mother has lost you! I saw you from among the most
understanding men in Madinah, don't the Jews and Christians read the
Tourat and the Injeel and don't understand what is in it?
Mishkat, Hadith 277, Nrrated by Ahmad and Ibn Majah
And this Hadith makes clear that Muhammad said that the Jews and Christians read their Book, but don't understand, He did not say that they were interpolated or copied, And maybe this points to the Arab christians and Jews that they don't understand the Language of the tourat which is Hebrew, and the Language of the Injeel which is Greek. So we ask, how many did read and understand the Bible?
So what about the Hadith of the starting of revelation, where in
Khadija takes Muhammad to Her cousin, and He was a christian, and He
wrote The Bible in Greek, so He wrote from the Injeel in Greek
whatever God Willed Him to write, and He was a very old and has gone
blind.
Bukari, book 1, page 2
This means that the Bible was known to the Arab
We can say, that the bible in the time of the Prophet was not interpolated.
