[Machine] A man from the companions of the Prophet ﷺ entered the mosque, and then he saw Ka'b cutting his hair. The man asked, "Who is this?" They said, "It is Ka'b cutting his hair." The man said, "I heard the Messenger of Allah ﷺ saying that no one should cut their hair except the leader, the appointed, or the arrogant." This was conveyed to Ka'b, and after that, he was not seen cutting his hair.  

دَخَلَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ الْمَسْجِدَ فَإِذَا كَعْبٌ يَقُصُّ فَقَالَ مَنْ هَذَا؟ قَالُوا كَعْبٌ يَقُصُّ فَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَا يَقُصُّ إِلَّا أَمِيرٌ أَوْ مَأْمُورٌ أَوْ مُخْتَالٌ قَالَ فَبَلَغَ ذَلِكَ كَعْبًا فَمَا رُئِيَ يَقُصُّ بَعْدُ
