question #2 Sahih al-Bukhari 6808, Book 86, Hadith 37 : How does the decrease in religious knowledge and increase in ignorance relate to the signs of the Last Day?

I will narrate to you a narration which nobody will narrate to you
after me. I heard that from the Prophet. I heard the Prophet (ﷺ) saying,
“The Hour will not be established” or said: “From among the portents
of the Hour is that the religious knowledge will betaken away (by the
death of religious Scholars) and general ignorance (of religion) will
appear; and the drinking of alcoholic drinks will be very common, and
(open) illegal sexual intercourse will prevail, and men will decrease
in number while women will increase so much so that, for fifty women
there will only be one man to look after them.”
