question #2 Sahih al-Bukhari 2804, Book 56, Hadith 21 : What is the significance of ultimate victory for prophets despite facing challenges?

That Abu Sufyan told him that Heraclius said to him, “I asked you about the outcome of your battles
with him (i.e. the Prophet (ﷺ) ) and you told me that you fought each other with alternate success. So the
Apostles are tested in this way but the ultimate victory is always theirs.
