Is the aforementioned Hadith regarding the Prophet, may Allah’s prayers and peace be upon him, seeing women being tormented during the Isra (Night Journey), and the subsequent statements about the punishment of a woman who verbally abuses her husband or denies his kindness, authentic or fabricated?

The first Hadith is fabricated. The Hadith attributed to Uthman (may Allah be pleased with him), with the wording: "Any woman who says to her husband: 'I have never seen any good from you,' except that Allah will nullify her deeds for seventy years, even if she fasts the day and prays at night," has not been found. However, it was narrated with the wording: "If a woman says to her husband: 'I have never seen any good from you,' then her deeds are nullified," and Al-Albani mentioned it in "Silsilah ad-Da'ifah" (The Series of Weak Hadith), stating that it is fabricated (mawdu'). As for the Hadith attributed to Abu Bakr (may Allah be pleased with him), with the wording: "Any woman who torments her husband with her tongue is under the curse of Allah and His wrath, and the curse of the angels and all people," it has not been found.
