It has been narrated on the authority of Hasan that A'idh b. 'Amr who was one of the Companions of the Messenger of Allah ﷺ called on 'Ubaidullah b. Ziyad and said (to him): O my son, I have heard the Messenger of Allah ﷺ say: The worst of guardians is the cruel ruler. Beware of being one of them. Ubaidullah said (to him out of arrogance): Sit you down. You are from the chaff of the Companions of Muhammad ﷺ. A'idh said: Was there worthless chaff among them? Such worthless chaff appeared after them and among other people.

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، حَدَّثَنَا الْحَسَنُ، أَنَّ عَائِذَ بْنَ عَمْرٍو، - وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ - دَخَلَ عَلَى عُبَيْدِ اللَّهِ بْنِ زِيَادٍ فَقَالَ أَىْ بُنَىَّ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ
" إِنَّ شَرَّ الرِّعَاءِ الْحُطَمَةُ فَإِيَّاكَ أَنْ تَكُونَ مِنْهُمْ " . فَقَالَ لَهُ اجْلِسْ فَإِنَّمَا أَنْتَ مِنْ نُخَالَةِ أَصْحَابِ مُحَمَّدٍ ﷺ . فَقَالَ وَهَلْ كَانَتْ لَهُمْ نُخَالَةٌ إِنَّمَا كَانَتِ النُّخَالَةُ بَعْدَهُمْ وَفِي غَيْرِهِمْ .
