Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن أبي عبد الله جابر بن سمرة رضي الله عنهما قال: "كنت أصلى مع النبي صلى الله عليه وسلم الصلوات، فكانت صلاته قصداً وخطبته قصداً" ((رواه مسلم)).
I used to perform prayer with the Prophet (ﷺ) and his Salat was of a moderate length and his Khutbah too was moderate in length.[Muslim].
