I am narrating to you a tradition. If I were not at death's door, I would not narrate it to you. I heard the Messenger of Allah (may peace he upon him) say: A ruler who, having obtained control over the affairs of the Muslims, does not strive for their betterment and does not serve them sincerely shall not enter Paradise with them.  

عَنْ أَبِي الْمَلِيحِ أَنَّإِنِّي مُحَدِّثُكَ بِحَدِيثٍ لَوْلاَ أَنِّي فِي الْمَوْتِ لَمْ أُحَدِّثْكَ بِهِ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مِنْ أَمِيرٍ يَلِي أَمْرَ الْمُسْلِمِينَ ثُمَّ لاَ يَجْهَدُ لَهُمْ وَيَنْصَحُ إِلاَّ لَمْ يَدْخُلْ مَعَهُمُ الْجَنَّةَ  

I am narrating to you a hadith which I would have never narrated to you had I not been in death-bed. I heard Allah's apostle ﷺ say: A ruler who has been entrusted with the affairs of the Muslims but he makes no endeavors ( for the material and moral uplift) and does not sincerely mean (their welfare) would not enter Paradise along with them. (Using translation from Muslim 142d)   

لَهُ مَعْقِلٌ ؓ إِنِّي مُحَدِّثُكَ بِحَدِيثٍ لَوْلَا أَنِّي فِي الْمَوْتِ لَمْ أُحَدِّثْكَ بِهِ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَا مِنْ أَمِيرٍ يَلِي أَمْرَ الْمُسْلِمِينَ ثُمَّ لَا يَجْهَدُ لَهُمْ وَلَا يَنْصَحُ إِلَّا لَمْ يَدْخُلْ مَعَهُمُ الْجَنَّةَ  

"مَا مِنْ أَمِيرٍ يَلي أَمْرَ المُسْلِمِينَ ثُمَّ لَا يَجْهَدُ لَهُمْ وَيَنْصَحُ، إلا لَمْ يَدْخُلْ مَعَهُمْ الجَنَّةَ".
