question #1 Sahih al-Bukhari 2681, Book 52, Hadith 42 : What are the key qualities that are associated with a prophet according to the conversation between Abu Sufyan and Heraclius?

Abu Sufyan told me that Heraclius said to him, “When I inquired you what he (i.e. Muhammad)
ordered you, you replied that he ordered you to establish the prayer, to speak the truth, to be chaste, to
keep promises and to pay back trusts.” Then Heraclius added, “These are really the qualities of a
prophet.”
