In the Holy Injeel, in John 8:42-46, we read that Hazrat Isa ( ع ) spoke to a crowd and said:
“Why do you not understand what I say? It is because you cannot bear to listen to my message. You are the children of your father, the Devil, and you want to follow your father’s desires. From the very beginning he was a murderer and has never been on the side of truth, because there is no truth in him.
“When he tells a lie, he is only doing what is natural to him, because he is a liar and the father of all lies.
“But I tell the truth, and that is why you do not believe me.
“Which one of you can prove that I am guilty of sin? If I tell the truth, then why do you not believe me?
His character is clearly revealed
Both the Holy Qur’an and the Blessed Injeel agree that Hazrat Isa ( ع ) never sinned.

قَالَ إِنَّمَا أَنَا رَسُولُ رَبِّكِ لأَهَبَ لَكِ غُلاَمًا زَكِيًّا
He said, “I am truly a messenger of your Lord to give you a sinless boy.”
Holy Qur’an | Mariam 19:19
οὐ γὰρ ἔχομενἀρχιερέα μὴ δυνάμενον συμπαθῆσαι ταῖς ἀσθενείαις ἡμῶν, πεπειρασμένον δὲ κατὰ πάντα καθ’ ὁμοιότητα χωρὶς ἁμαρτίας
“For we do not have a high priest incapable of sympathizing with our weaknesses, but one who has been tempted in every way just as we are, yet without sin.”
Blessed Injeel | Hebrews 4:15
Some thoughts
In Mariam 19:19 the Holy Qur’an says Hazrat Isa ( ع ) is ‘sinless’. That word this is not used in any other verse. This is a remarkable thing.
Also, in the Holy Qur’an and Blessed Injeel there is no record that Hazrat Isa ( ع ) ever asked for his sins to be forgiven.
