Hadith of a man from the companions of the Prophet (peace be upon him)

حَدِيثُ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، ١٨٠٥٠ - حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا الْعَوَّامُ، حَدَّثَنَا عَبْدُ الْجَبَّارِ الْخَوْلَانِيُّ، قَالَ: دَخَلَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ الْمَسْجِدَ، فَإِذَا كَعْبٌ يَقُصُّ فَقَالَ: مَنْ هَذَا؟ قَالُوا: كَعْبٌ يَقُصُّ، فَقَالَ: سَمِعْتُ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: " لَا يَقُصُّ إِلَّا أَمِيرٌ، أَوْ مَأْمُورٌ، أَوْ مُخْتَالٌ " قَالَ: فَبَلَغَ ذَلِكَ كَعْبًا: " فَمَا رُئِيَ يَقُصُّ بَعْدُ " (١)، ،

Abdul Jabbar Khawlani (may Allah be pleased with him) says that once a companion (may Allah be pleased with him) entered the mosque while Ka'b Ahbar (may Allah have mercy on him) was delivering a sermon. He asked, "Who is this?" The people informed him, "This is Ka'b, who is delivering a sermon." He said, "I heard the Prophet (peace and blessings of Allah be upon him) say that only the leader may deliver a sermon, or one who has been given permission, or a show-off." When Ka'b (may Allah have mercy on him) learned of this, he was not seen delivering sermons after that.
