Sunan an-Nasa'i 4211
it was narrated from Abu Hurairah that the Prophet said:
"You will become keen for positions of authority, but that will become a regret and loss. What a good life they will live, but how hard it will be for them when they die."
أَخْبَرَنِي مُحَمَّدُ بْنُ آدَمَ بْنِ سُلَيْمَانَ، عَنِ ابْنِ الْمُبَارَكِ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ إِنَّكُمْ سَتَحْرِصُونَ عَلَى الإِمَارَةِ وَإِنَّهَا سَتَكُونُ نَدَامَةً وَحَسْرَةً فَنِعْمَتِ الْمُرْضِعَةُ وَبِئْسَتِ الْفَاطِمَةُ ‏"‏ ‏.‏
