This is important because these are things the anti-Christ will say.
The real Issa, son of Maryam, will be recognized for he will rebuke worship of himself, forbid idolatry and command worship of Allah alone (John 17:3; Matthew 7:23)
Good news is it appears Issa has (in future tense) prayed for the forgiveness of those who took him as a diety, which is a grave sin idolatry, owing to it being the result of confusion.
That is by the way how Christian's are viewed in Islam - deeply confused owing to the mischief done to the creed by the Niceans. The Jews are viewed as arrogant/haught.
The following verses imply forgiveness is possible for sincere, truthful Christians.
"And [beware the Day] when Allah will say, "O Jesus, Son of Mary, did you say to the people, 'Take me and my mother as deities besides Allah ?'" He will say, "Exalted are You! It was not for me to say that to which I have no right. If I had said it, You would have known it. You know what is within myself, and I do not know what is within Yourself. Indeed, it is You who is Knower of the unseen. I said not to them except what You commanded me - to worship Allah, my Lord and your Lord. And I was a witness over them as long as I was among them; but when You took me up, You were the Observer over them, and You are, over all things, Witness. If You should punish them - indeed they are Your servants; but if You forgive them - indeed it is You who is the Exalted in Might, the Wise. Allah will say, "This is the Day when the truthful will benefit from their truthfulness." For them are gardens [in Paradise] beneath which rivers flow, wherein they will abide forever, Allah being pleased with them, and they with Him. That is the great attainment."
Surah Maidah, 116-119
