Is the analysis that states that fasting Ashura is a lie, and that the narration of the Prophet seeing the Jews fasting Ashura when he went to Medina is fabricated, correct?

The analysis of the person mentioned is incorrect, and their fatwa is invalid, because the Prophet, peace and blessings be upon him, fasted Ashura and commanded its fasting. The hadith is narrated in the Two Sahihs, which refutes the claim of its fabrication. The Prophet, peace and blessings be upon him, did not know the unseen except what Allah revealed to him, and his inquiry about the reason for the Jews fasting Ashura does not diminish him. Moreover, the Prophet's fasting of Ashura was not in imitation of the Jews, for Quraysh used to fast it before that, and the Prophet, peace and blessings be upon him, used to fast it before the Hijra. What came in the hadith was a description of a situation and an answer to a question. As for his statement, "He will fast the ninth next year," there is no contradiction between the beginning and the end of the hadith, for the Prophet, peace and blessings be upon him, fasted it and then wished to differ from the Jews in the latter part of his life.
