Hadith 1374
۞
I have come to know of your anger at the posting of al-Ashtar in your place, but I did not do so because of any shortcoming on your part or to get you to increase your efforts, but when I had taken away what was under your authority I would have placed you at a position which would have been less exacting and more attractive to you.
أَمَّا بَعْدُ، وَقَدْ بَلَغَنِي مَوْجِدَتُكَ مِنْ تَسْرِيحِ الْأَشْتَرِ إِلَى عَمَلِكَ وَإِنِّي لَمْ أَفْعَلْ ذلِكَ اسْتِبْطَاءً لَكَ فِي الجَهْدِ، وَلَا ازْدِيَاداً لَكَ فِي الْجِدِّ، وَلَوْ نَزَعْتُ مَا تَحْتَ يَدِكَ مِنْ سُلْطَانِكَ، لَوَلَّيْتُكَ مَا هُوَ أَيْسَرُ عَلَيْكَ مَؤُونَةً، وَأَعْجَبُ إِلَيْكَ وِلَايَةً
