Isa will be confronted with his argument, and Allah will inspire him with the response in His statement, "And when Allah said, 'Isa, son of Maryam, did you say to people, take me and my mother as two gods besides Allah?'" [Maidah 5:116].Abu Hurairah reported from the Prophet ﷺ that Allah will inspire him with the reply, "Glory be to You! It was not for me to say what I had no right to say," and the rest of the verse.
حدثنا ابن أبي عمر حدثنا سفيان بن عيينة عن عمرو بن دينار عن طاووس
يلقى عيسى حجته فلقاه الله في قوله {وإذ قال الله يا عيسى ابن مريم أأنت قلت للناس اتخذوني وأمي إلهين من دون الله} قال أبو هريرة عن النبي ﷺ فلقاه الله {سبحانك ما يكون لي أن أقول ما ليس لي بحق} الآية كلها
