question #3 Sahih al-Bukhari 458, Book 8, Hadith 106 : What can be learned from the Prophet’s (ﷺ) actions regarding the respect and recognition of those who contribute to the community?

A black man or a black woman used to sweep the mosque and he or she died. The Prophet (ﷺ) asked
about her (or him). He was told that she (or he) had died. He said, “Why did you not inform me?
Show me his grave (or her grave).” So he went to her (his) grave and offered her (his) funeral prayer.”
