question #3 Sahih al-Bukhari 7032, Book 91, Hadith 47 : What can be inferred about the relationship between the Prophet Muhammad (ﷺ) and Umar bin Al-Khattab from this dream?

I heard Allah’s Messenger (ﷺ) saying, “While I was sleeping, I saw that a cup full of milk was brought to me
and I drank of it and gave the remaining of it to `Umar bin Al-Khattab.” They asked. What have you
interpreted (about the dream)? O Allah’s Messenger (ﷺ)?” The Prophet (ﷺ) said. “(It is Religious) knowledge.”
