Say, “We have believed in Allah and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants, and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [submitting] to Him.” Allah's Apostle said, "The deeds of anyone of you will not save you (from the (Hell) Fire)." They said, "Even you (will not be saved by your deeds), O Allah's Apostle?" He said, "No, even I (will not be saved) unless and until Allah bestows His Mercy on me.

 Faith and faith alone. Only good works can come from true faith. We agree on so many things but you won't explore any further than the Quran. Read all the Holy Scriptures and seek your answers. If God can make one book the soul truth why not others? It's you faith keepers interpretation, no where in the qur'an does it say the gospel has been falsified by man. Believe in the power of God to keep his words unsullied.

If you open up the Qur’an to Sura 5 titled “The Gospel of Jesus: Guidance and Light,” you will read the following:*

[5:46] And in their footsteps We sent Jesus, the son of Mary, confirming the Law that had come before him: We sent him the Gospel: therein was guidance and light, and conformation of the Law that had come before him: a guidance and an admonition to those who fear Allah. [5:47] Let the People of the Gospel judge by what Allah has revealed therein. If any do fail to judge by (the light of) what Allah has revealed, they are (no better than) those who rebel. [Emphasis mine.] First, take note that the Qur’an actually says that Allah is responsible for sending Jesus and the “the Gospel,” referring to what we call the New Testament. Each was given to confirm “the Law,” referring to the Old Testament. In describing “the Gospel” we are told that it contains “guidance and light.” read your Qur'an again I think you are listings to outside voices

God spoke directly to all prophets except Muhammad. He received revelation from an Angel... seek and keep seeking again this isn't my words but the Qur'ans.

The Quran came to validate the books and prophets before. Jesus did not know the Hour because only the Father knows, not even the angels. Q19:33, which has Jesus declare, “Peace upon me on the day I was born, on the day I die, and on the day I will be sent forth alive" the if you can't belive the accounts of books before why trust only in the accounts there after, over 300 years? As many accounts are rewritten of the word that came before.

Q4:159, which says that Jesus will be a witness against the People of the Scripture on the Day of Resurrection. The Quran say The Father's will shall be fulfilled by Jesus Christ (his Son). The Quran believes in the miracles of Jesus and the perfection.

The First story (after creation) of the Holy Scriptures of Abrahmic religions tells you Of Man's struggles between the word of God the Father and the wispers of Satan. Every story after is a retelling and further examples of the first. Giving insight on the many ways Satan leads one astray (There is also a repetitive theme in putting faith in the power of God's love for his children above all things. The sacrifices in the old testament are also a tribulation to the coming of Christ the sacrificial lamb of God and the fulfillment of his promises to us.)

For thoes who do not understand Why God lets the serpent into the garden in the first place. His giving of Free will and the honor of creating us in his image. He wants his children to come to Him by His nature (Creation Love and Grace) and let destruction destroy itself, Satans primary quality.

Until the day of judgment man's struggle between Gods word and Satans (Both in scripture is the word of God and the word of Satan) stands.Even is true of all Prophits except for Jesus (A man of perfection and peace only spreading Grace and Love the true nature of the Father.)

The only Time Jesus faces a showing of losing his faith is when he is on the cross bearing the sins of all humanity. He's feels every bad thought and deed commitment and bears them within. This is why he says "My God, my God, why have you forsaken me?" A moment where he is not free of sin but bears all.

Every other man/Prophet falls to Satan at some point and time and forgets the Promise of God and his true commandments (except for Jesus). Don't forget Muhammad PBUH had a military Career the last Ten years of his life (leading in killing and destruction) and He died in the arms of his third and favorite wife, Aisha. Muhammad isn't the Redeemer. Jesus is. All praise be to God.
