How can it be justified that Al-Bukhari did not mention the Hadith: "There are two types of the people of Hell whom I have not seen..." regarding the Isra and Mi'raj, and why did Muslim narrate it from Abu Hurairah, whose narrations are doubted?

The Hadith of Abu Hurairah (may Allah be pleased with him) about "Two types of people from the inhabitants of Hell whom I have not seen" is an authentic Hadith narrated by Muslim and others. Imams have consistently used it as evidence and have not deemed it weak; it is one of the proofs of prophethood. Although some of its narrations were transmitted as mauquf (a saying or action of a Companion) by Malik, this does not invalidate the marfu' (a saying or action of the Prophet) narration, especially since Muslim ibn Abi Maryam, Malik's shaykh, sometimes hesitated to narrate a hadith directly from the Prophet, and the content of the Hadith cannot be a personal opinion but rather a revelation. The fact that Bukhari did not include it in his Sahih does not mean it is weak, as he did not include all authentic hadiths. Abu Hurairah is the Imam of the memorizers (of Hadith) and the narrator of Islam, and questioning him comes from the people of innovation and orientalists.
