question #2 Sahih al-Bukhari 7137, Book 93, Hadith 1 : How is obedience to a ruler appointed by the Prophet linked to obedience to the Prophet himself?

Allah’s Messenger (ﷺ) said, “Whoever obeys me, obeys Allah, and whoever disobeys me, disobeys Allah,
and whoever obeys the ruler I appoint, obeys me, and whoever disobeys him, disobeys me.”
