[Machine] I used to pray with the Prophet ﷺ, and his prayers were concise and his sermons were concise as well.  

كُنْتُ أُصَلِّي مَعَ النَّبِيِّ ﷺ فَكَانَتْ صَلَاتُهُ قَصْدًا وَخُطْبَتُهُ قَصْدًا  

The Messenger of Allah ﷺ would not lengthen the sermon on Friday. He would say a few words. (Using translation from Abū Dāʾūd 1107)   

كَانَ رَسُولُ اللهِ ﷺ لَا يُطِيلُ الْمَوْعِظَةَ يَوْمَ الْجُمُعَةِ إِنَّمَا هِيَ كَلِمَاتٌ يَسِيرَةٌ  

'Ammar delivered to us the sermon. It was short and eloquent. When he (, Ammir) descended (from the pulpit) we said to him: 0 Abd al-Yaqzn, you have delivered a short and eloquent sermon. Would that you had lengthened (the sermon). He said: I have heard the Messenger of Allah ﷺ as saying: The lengthening of prayer by a man and the shortness of the sermon is the sign of his understanding (of faith). So lengthen the prayer and shorten the sermon, for there is charm (in precise) expression. (Using translation from Muslim 869)   

خَطَبَنَا عَمَّارٌ ؓ فَأَبْلَغَ وَأَوْجَزَ فَلَمَّا نَزَلَ قُلْنَا يَا أَبَا الْيَقْظَانِ لَقَدْ أَبَلَغْتَ وَأَوْجَزْتَ فَلَوْ كُنْتَ تَنَفَّسْتَ؟ فَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ طُولَ صَلَاةِ الرَّجُلِ وَقِصَرَ خُطْبَتِهِ مَئِنَّةٌ مِنْ فَقْهِهِ فَأَطِيلُوا الصَّلَاةَ وَأَقْصِرُوا الْخُطَبَ وَإِنَّ مِنَ الْبَيَانِ لَسِحْرًا  

[Machine] Abdullah said, "Indeed, the length of the prayer and the shortness of the sermon are indications of a person's understanding (fIQh)."  

قَالَ عَبْدُ اللهِ إِنَّ طُولَ الصَّلَاةِ وَقِصَرَ الْخُطْبَةِ مَئِنَّةٌ مِنْ فِقْهِ الرَّجُلِ يَقُولُ عَلَامَةٌ  

[Machine] Lengthen this prayer and shorten this sermon, meaning the Friday prayer. And it was also narrated from another perspective by Ammar, raised briefly.  

أَطِيلُوا هَذِهِ الصَّلَاةَ وَأَقْصِرُوا هَذِهِ الْخُطْبَةَ يَعْنِي صَلَاةَ الْجُمُعَةِ وَرُوِيَ ذَلِكَ مِنْ وَجْهٍ آخَرَ عَنْ عَمَّارٍ مَرْفُوعًا مُخْتَصَرًا  

The Messenger of Allah ﷺ commanded us to shorten the speeches. (Using translation from Abū Dāʾūd 1106)   

أَمَرَنَا رَسُولُ اللهِ ﷺ بِإِقْصَارِ الْخُطَبِ
