Greetings Bibleblevr,
I see some of your questions have been answered, but I hope you don't mind if I go back to some of the very basics, starting with the concept of God in Islam. You may know some of this already, but I will re-state it here in any case.
• We believe in One God, other than Whom there is none worthy of worship.
• He has no associates whatsoever in His Divinity.
• He has no sons, daughters, brothers, sisters, cousins, grandparents or relatives of any kind.
• He does not beget, not is He begotten.
• He is not composed of any number of persons, godheads, essences or anything else.
• He is Eternal, Immortal, indivisible.
• He is free of all need and dependence.
No trinity, no sons, no 3-in-1s, just One.
Prophets
We believe in all the Prophets (peace be upon them all) that God sent, from A-Z . We do not reject any of them. Neither do we exaggerate the status of any of them to something it wasn't, i.e. divine. We believe in them as they were: the noblest of human beings chosen by God to guide and warn mankind. Islam is the only religion that accepts all of them, and does not discriminate against any of them. Jesus (peace be upon him) occupies an esteemed position in Islam as being one of the mightiest Messengers of God. Prophet Muhammad (peace be upon him) is the final messenger of God to all mankind till the end of time, and what he brought is unchanged and untampered with.
If a person calls himself a Muslim and doesn't believe in, respect, or love Jesus (peace be upon him) then he is NOT a Muslim.
- We believe that Jesus (peace be upon him) was one of the mightiest messengers of God.
- We believe that he was the messiah.
- We believe he was born miraculously without any male intervention.
- We believe that he gave life to the dead with Gods permission.
- We believe he healed lepers and those born blind, with Gods permission
However we do not believe that Jesus (peace be upon him) ever claimed divinity, or that he was God, son of God, or that he said "Worship me". We also do not believe that he was crucified, nor died for anyones' sins. In Islam, each person is accountable for their sins.
Holy Book
We believe that God revealed the Torah, the Zaboor given to Prophet David (peace be upon him), the Injeel given to Jesus (peace be upon him), but that over time, humans have changed these books and intermingled their own words with Gods words. The scripture that God gave Jesus (peace be upon him) was God's word. But Christians themselves admit that the Bible we have with us now is not the word of God, but mainly the word of man, and that some parts are written by people that never met Jesus (peace be upon him) and some parts, no one really knows exactly who wrote.
The Qur'an is the final book of God, to all mankind. It is 100% the word of God. Not a letter has changed. There are no versions. There are no contradictions. It is scientifically sound. It confirms the original message that God sent in the earlier scriptures.
Sins
In Islam we do not believe in the concept of original sin. We believe that all babies are born pure, innocent and free of sins, and are untainted by the burden of sins it is impossible for them to have committed. We do not believe that God made one person die for the sins of the whole world. In Islam, each person is responsible for their own sins.
The message
We believe that prophet Jesus (peace be upon him) came to preach the same message that Prophet Moses (peace be upon him) had preached before him, and not to alter or abolish it. All the Prophets (peace be upon them) preached the same message that God had sent them to preach; to worship ONE God. The message didn't suddenly change when it came to Jesus (peace be upon him), with a trinity or god suddenly begetting offspring. The message is and was what it always has been since the time of Adam (peace be upon him), he same message that Jesus (peace be upon him) preached, the same message given to all the Prophets, culminating in the final Prophet, Muhammad (peace be upon him), namely to worship One God, with no associates whatsoever in His Divinity, and to follow the guidance God has sent. Prophet Muhammad (peace be upon him) is the last Prophet, sent to all humanity, and what he brought is the guidance that must be followed til the Day of Judgement.
Allah depicts in the Qur'an what he will say to Prophet Jesus (peace be upon him) on the Day of Judgement, in front of all humanity, and what Jesus's (peace be upon him) reply will be:
And when Allah will say: "O Jesus, son of Mary! Did you say unto mankind: Take me and my mother for two gods beside Allah?" He will say: "Be Glorified!
It was not mine to utter that to which I had no right. If I used to say it, then You knew it. You know what is in my mind, and I know not what is in Your Mind. Lo! You, only You, are the Knower of Things Hidden.
I spoke unto them only that which You commanded me, (saying): Worship Allah, my Lord and your Lord. I was a witness of them while I dwelt among them, and when You took me, You were the Watcher over them. You are Witness over all things." (Qur'an 5:116-117)
Peace.
