عَنْ عَبْدِ الْجَبَّارِ الْخَوْلَانِيِّ قَالَ دَخَلَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْمَسْجِدَ فَإِذَا كَعْبٌ يَقُصُّ فَقَالَ مَنْ هَذَا قَالُوا كَعْبٌ يَقُصُّ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ لَا يَقُصُّ إِلَّا أَمِيرٌ أَوْ مَأْمُورٌ أَوْ مُخْتَالٌ قَالَ فَبَلَغَ ذَلِكَ كَعْبًا فَمَا رُئِيَ يَقُصُّ بَعْدُ
It is narrated from Abdul Jabbar Khawlani, he says: A companion entered the mosque while Sayyiduna Ka'b was giving a sermon. He said: What is this? The people said: Sayyiduna Ka'b (may Allah be pleased with him) is giving a sermon. He said: I heard the Messenger of Allah (peace and blessings be upon him) say: No one relates stories except an Amir, or one who is commanded, or an arrogant person. When Sayyiduna Ka'b (may Allah be pleased with him) came to know of this, he was not found giving sermons thereafter.
