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. (Using translation from Muslim 1830)
أَنَّ عَائِذَ بْنَ عَمْرٍو وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ دَخَلَ عَلَى عُبَيْدِ اللهِ بْنِ زِيَادٍ فَقَالَ إِنِّي سَمِعْتُ رَسُولَ اللهِ 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 النَّخْلَةُ بَعْدَهُمْ وَفِي غَيْرِهِمْ
