HARSHNESS H H 193 "Son, I (A'iaih son of Amr) heard the Messenger of Allah, praise and peace be upon him, say: 'The worst ruler is the one who deals harshly with people. Beware, in case you become one.' Ubaidullah said to him: 'Sit down, you are just like chaff among the Companions of the Messenger of Allah, praise and peace be upon him," He asked: 'And was there chaff among them? Surely, chaff came later among others.'" R 193 Muslim with a chain up to Abu Sa'id Hasan Basri who related that A'aih son of Amr visited Ubaidullah son of Zaid and said to him this.
192- التاسع : عن أَبي سعيد الحسن البصري : أن عائِذَ بن عمرو رضي الله عنه دخل عَلَى عُبَيْدِ اللهِ بنِ زياد ، فَقَالَ : أي بُنَيَّ ، إني سمعت رَسُول الله صلى الله عليه وآله وسلم ، يقول : "إنَّ شَرَّ الرِّعَاءِ الحُطَمَةُ" فَإِيَّاكَ أنْ تَكُونَ مِنْهُمْ ، فَقَالَ لَهُ : اجلِسْ فَإِنَّمَا أنْتَ مِنْ نُخَالَةِ أصْحَابِ مُحَمَّد صلى الله عليه وآله وسلم ، فَقَالَ : وهل كَانَتْ لَهُم نُخَالَةٌ إِنَّمَا كَانَتِ النُّخَالَةُ بَعْدَهُمْ وَفي غَيْرِهِمْ . رواه مسلم .
