question #2 Sahih al-Bukhari 3959, Book 64, Hadith 11 : What is the significance of the comparison between the warriors of Badr and the companions of Saul?

We used to say that the warriors of Badr were over three-hundred-and-ten, as many as the
Companions of Saul who crossed the river with him; and none crossed the river with him but a
believer.
