question #2 Sahih al-Bukhari 3338, Book 60, Hadith 13 : How did Prophet Noah warn his nation about the Dajjal, and what is the significance of this warning?

Allah’s Messenger (ﷺ) said, “Shall I not tell you about the Dajjal a story of which no prophet told his nation?
The Dajjall is one-eyed and will bring with him what will resemble Hell and Paradise, and what he
will call Paradise will be actually Hell; so I warn you (against him) as Noah warned his nation against
him.”
