The Messenger of Allah (ﷺ) gave two sermons between which he sat, recited the Quran and gave the people an exhortation.
Sunan Abi Dawud Book 2, Hadith 705
← Previous Hadith The Messenger of Allah (ﷺ) used to deliver the sermon standing, then he would sit down, then stand and preach standing. If anyone tells you he preached sitting, he is lying. I swear by Allah that I offered along with more than two thousand prayers.

Sunan Abi Dawud Book 2, Hadith 704 Next Hadith → I saw the Prophet (ﷺ) would deliver the sermon standing, then sit down without saying anything. The narrator then reported the tradition in full.
