question #3 Sahih al-Bukhari 1061, Book 16, Hadith 20 : What is the significance of praising Allah before delivering a sermon?

And this was narrated by Asma’ who said, “Allah’s Messenger (ﷺ) finished the eclipse prayer and by then the sun (eclipse) had cleared. Then he delivered the Khutba (religious talk) and praised Allah as He deserved and then said Amma ba’du.”
