question #3 Sahih al-Bukhari 3653, Book 62, Hadith 5 : What can be learned about the relationship between the Prophet Muhammad (ﷺ) and Abu Bakr from this event?

I said to the Prophet (ﷺ) while I was in the Cave. “If any of them should look under his feet, he would see
us.” He said, “O Abu Bakr! What do you think of two (persons) the third of whom is Allah?”
