Jesus (in the gospels) was upon Tawheed
Jesus was upon Tawheed according the Gospel of Matthew
In chapter 14 of the Gospel of Matthew, verse 23, it states: "And after he had dismissed the crowds, he (Jesus) went up to the mountain by himself to pray."
Dr.Rabee' ibn Haadee, the author of the Book 'The station of Jesus in Islaam' comments on this verse by saying: 'Prayer is one of the greatest acts of worship that can be performed to God, and no one engages in it except for a lowly servant who stands in need of mercy of his Lord and Creator. This is as God says in the Qur'aan: "O Mankind! It is you who stand in need of God, whereas God is Rich, free of all needs, Most Praiseworthy." (35:15)
Again, we see in the Gospel of Matthew, verse 39, it states that the Messiah: "fell on his face and prayed, 'My Father, if it be possible, let this cup pass from me; nevertheless, not as I will; but as Thou wilt."
Again, Dr.Rabee ibn Haadee comments: "So in this text, there is proof that Jesus was a worshipper of God who had no control over repelling harm from himself or bring benefit to himself. And there is evidence in this text that he sought refuge and protection in God during the hard times, seeking His Assistance and humbling himself before Him, in order to remove the harm and danger that was approaching him. So he fell prostrate with his face on the ground, seeking nearness to Him, lowering himself before Him, showing his need for Him and expressing belief that no one has the ability to repel harm except Him. This is the state of all the messengers, not to mention, all of mankind."
In addition to these verses, we find in chapter 12 of the Gospel of Mark, verses 28-30, the following narration: "And one of the scribes came up and heard them disputing with one another, and seeing that he (Jesus) answered them well, asked him, 'Which commandment is the first of all?' Jesus answered, 'The First is: Hear O Israel! The Lord our God, the Lord is One. And you shall love the Lord your God with all of your heart...to the end of this verse"
And in verse 32 of the same chapter, it states that: "The scribe said to him, 'You are right, teacher. You have truly said that He is One, and there is no other but He."
Then in verse 34, there occurs: "And when Jesus saw that he had answered wisely, he said to him, 'You are not far from the Kingdom of God.'"
