How can we reconcile the impermissibility of Nikah al-Mut'ah from the perspective that the Prophet Muhammad does not speak out of his own desire, and that this contradicts Allah's law, with the claim of authenticity of Hadiths that permit it based on the trustworthiness of the narrators? And are the narrators more truthful, or the Holy Qur’an and the Messenger of Allah?

A Muslim must use the Islamic greeting, "As-salamu alaykum wa rahmatullahi wa barakatuh" (Peace, mercy, and blessings of Allah be upon you), instead of "Peace be upon whoever follows guidance." Nikah al-Mut'ah (temporary marriage) was permissible at the beginning of Islam, then its prohibition was abrogated by consensus. This was inferred from the generality of Surah An-Nisa (4:24), and the majority of scholars have agreed on its prohibition until the Day of Judgment. The Prophet (peace be upon him) cannot contradict the law of his Lord, for he is infallible. It is not permissible to issue religious rulings without knowledge, and one must adhere to the principles of Fiqh (Islamic jurisprudence). Gifting flowers is permissible unless it is intended as an imitation of disbelievers. One must beware of speaking about Allah without knowledge, as this is equated with Shirk (polytheism).
