[Machine] I heard the Messenger of Allah, peace be upon him, saying, "Indeed, the length of a man's prayer and the brevity of his sermon are indicative of his understanding of the religion, so prolong your prayers and shorten your sermons, for surely, eloquence lies in clear expression."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِنَّ طُولَ صَلَاةِ الرَّجُلِ وَقِصَرَ خُطْبَتِهِ مَئِنَّةٌ مِنْ فِقْهِهِ فَأَطِيلُوا هَذِهِ الصَّلَاةَ وَاقْصُرُوا هَذِهِ الْخُطَبَ فَإِنَّ مِنَ الْبَيَانِ لسِحْرًا»  

"I used to pray with the Prophet ﷺ and his prayer was moderate in length and his Khutbah was moderate in length." (Using translation from Nasāʾī 1582)   

«صَلَّيْتُ مَعَ النَّبِيِّ ﷺ فَكَانَتْ صَلَاتُهُ قَصْدًا وَخُطْبَتُهُ قَصْدًا»
