question #2 Sahih al-Bukhari 3605, Book 61, Hadith 112 : How did Abu Huraira convey the Prophet’s warning about the potential threats to the Muslim community?

I was with Marwan and Abu Huraira and heard Abu Huraira saying, “I heard the trustworthy, truly
inspired one (i.e. the Prophet (ﷺ) ) saying, ‘The destruction of my followers will be brought about by the
hands of some youngsters from Quraish.” Marwan asked, “Youngsters?” Abu Huraira said, “If you
wish, I would name them: They are the children of so-and-so and the children of so-and-so.”
