question #1 Sahih al-Bukhari 100, Book 3, Hadith 42 : What are the consequences of losing knowledgeable religious leaders in a community?

I heard Allah’s Messenger (ﷺ) saying, “Allah does not take away the knowledge, by taking it away from (the
hearts of) the people, but takes it away by the death of the religious learned men till when none of the
(religious learned men) remains, people will take as their leaders ignorant persons who when
consulted will give their verdict without knowledge. So they will go astray and will lead the people
astray.”
