I used to pray with the Prophet (may Allah's peace and blessings be upon him) and his prayer was moderate in length and his sermon was moderate in length
Authentic hadithعن أبي عبد الله جابر بن سمرة رضي الله عنهما قال: كنت أصلي مع النبي صلى الله عليه وسلم الصلوات، فكانت صلاته قَصْدًا وخطبته قَصْدًا.
Abu ‘Abdullāh Jābir ibn Samurah (may Allah be pleased with him) reported: I used to pray with the Prophet (may Allah's peace and blessings be upon him) and his prayer was moderate in length and his sermon was moderate in length.
Explanation
The Prophet's prayer and sermon were not overly long or brief. Yet, they were moderate, being performed and given by the role model for Muslims in general and for Imāms and preachers in particular. So, no one should cite this Hadīth as evidence that the prayer and sermon may take place very quickly, for the Prophet's guidance points to moderation, and sometimes prolongation that causes no boredom.
