Mishkat al-Masabih 18 The Offices of Commander and Qadi كتاب الإمارة والقضاء 47

وَعَنْ أَبِي أُمَامَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ الْأَمِيرَ إِذَا ابْتَغَى الرِّيبَةَ فِي النَّاسِ أَفْسَدَهُمْ» . رَوَاهُ أَبُو دَاوُدَ

Abu Umama reported the Prophet as saying, ‘‘When a ruler seeks to make imputations against the people he corrupts them.” Abu Dawud transmitted it.
