If a Muslim doubts Bible, he doubts the definition of Jesus. Because the Bible is introduction to Jesus. Hence, Koran depends on Bible.
"In War and in Love there are no rules." (c)
I must correct you on this. The Quran does NOT depend on a book that God himself doesn't even endorse nor does Jesus. The Bible is made up of unknown authors, historians, theologians and who else knows but no where in the world does the Quran depend on a book with over 4000 discrepancies in it. The Muslim depends on the Quran and Sunnah of Mohammad pbuh ONLY. I can't imagine someone saying that God makes mistakes and then attributing a book that has mistakes, unto Him. Muslims and non muslims have every reason to say that the Bible is not authentic.
The definition of Jesus in Islam is follows:
He is indeed a miracle and was created by his Creator.
He is not God nor did he ever claim to be.
He is a mighty messenger of God who was sent down to deliver the oneness of Allah.
He performed miracles as like other messengers of God.
He did not die for he was taken up and will be coming back down at his appointed time.
He will fight the antichrist and kill him.
“O people of the Scripture (Christians)! Do not exceed the limits in your religion, nor say of Allah aught but the truth. The Messiah ‘Eesa (Jesus), son of Maryam (Mary), was (no more than) a Messenger of Allah and His Word, (‘Be!’ and he was) which He bestowed on Maryam (Mary) and a spirit (Rooh) created by Him; so believe in Allah and His Messengers. Say not: ‘Three (trinity)!’ Cease! (it is) better for you. For Allah is (the only) One Ilah (God), glory is to Him (Far Exalted is He) above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allah is All-Sufficient as a Disposer of affairs”
al-Nisa’ 4:171
“The Messiah [‘Eesa (Jesus)], son of Maryam (Mary), was no more than a Messenger; many were the Messengers that passed away before him. His mother [Maryam (Mary)] was a Siddeeqah [i.e. she believed in the Words of Allah and His Books]. They both used to eat food (as any other human being, while Allah does not eat). Look how We make the Ayaat (proofs, evidences, verses, lessons, signs, revelations, etc.) clear to them; yet look how they are deluded away (from the truth)”
al-Maa’idah 5:75
