CHAPTER: Giving The Khutbah While Standing.
Jabir bin Samurah said: The Messenger of Allah صلی اللہ علیہ وسلم 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.
Jabir bin Samurah said: The Messenger of Allah صلی اللہ علیہ وسلم gave two sermons between which he sat, recited the Quran and gave the people an exhortation.
Jabir bin Samurah said: I saw the Prophet صلی اللہ علیہ وسلم would deliver the sermon standing, then sit down without saying anything. The narrator then reported the tradition in full.
