The Bible is most definitely without doubt considered as revelation that was revealed to the Prophet Jesus (Peace be upon him) also known as Isa (AS) in Islam. The Prophet Jesus is considered as one of the greatest men and is mentioned several times in the Quran.
The Bible was perfect and pure at the time of revelation but because of deviation of theology, many different versions of the the holy books has surfaced.

Unfortunately I have not done any comparative religious studies therefore I am unable to answer you further regarding this, but feel free to question me on the religion of Islam and I will try and answer you to the best of my ability
