Sahih Muslim Book - 33, Hadith - 4731

وَحَدَّثَنَا أَبُو غَسَّانَ الْمِسْمَعِىُّ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ وَمُحَمَّدُ بْنُ الْمُثَنَّى قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ الآخَرَانِ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ حَدَّثَنِى أَبِى عَنْ قَتَادَةَ عَنْ أَبِى الْمَلِيحِ أَنَّ عُبَيْدَ اللَّهِ بْنَ زِيَادٍ دَخَلَ عَلَى مَعْقِلِ بْنِ يَسَارٍ فِى مَرَضِهِ فَقَالَ لَهُ مَعْقِلٌ إِنِّى مُحَدِّثُكَ بِحَدِيثٍ لَوْلاَ أَنِّى فِى الْمَوْتِ لَمْ أُحَدِّثْكَ بِهِ سَمِعْتُ رَسُولَ اللَّهِ -صلى الله عليه وسلم- يَقُولُ « مَا مِنْ أَمِيرٍ يَلِى أَمْرَ الْمُسْلِمِينَ ثُمَّ لاَ يَجْهَدُ لَهُمْ وَيَنْصَحُ إِلاَّ لَمْ يَدْخُلْ مَعَهُمُ الْجَنَّةَ ».

It was narrated from Abu Al-Malih that 'Ubaidullah bin Ziyad entered upon Ma'qil bin Yasar when he was sick, and Ma'qil said to him: "I am going to tell you a Hadith; were it not that I am about to die, I would not have narrated it to you. I heard the Messenger of Allah (s.a.w) say: 'There is no leader who has reached a position of authority over the Muslims, then he does not strive for their sake or act with sincerity towards them, but he will not enter Paradise with them."'
