“The Prophet ﷺ used to deliver the sermon standing, then he would sit down, then he would stand up and recite some Verses and remember Allah. His sermon was moderate, and his prayer was moderate (i.e., neither too long nor too short).” (Using translation from Ibn Mājah 1106)  

كَانَ النَّبِيُّ ﷺ «يَخْطُبُ قَائِمًا ثُمَّ يَجْلِسُ ثُمَّ يَقُومُ وَيَقْرَأُ آيَاتٍ وَيَذْكَرُ اللهَ وَكَانَتْ خُطْبَتُهُ قَصْدًا وَصَلَاتُهُ قَصْدًا»
