Sahih Muslim
Sahih Muslim 142a
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا أَبُو الأَشْهَبِ، عَنِ الْحَسَنِ، قَالَ عَادَ عُبَيْدُ اللَّهِ بْنُ زِيَادٍ مَعْقِلَ بْنَ يَسَارٍ الْمُزَنِيَّ فِي مَرَضِهِ الَّذِي مَاتَ فِيهِ . قَالَ مَعْقِلٌ إِنِّي مُحَدِّثُكَ حَدِيثًا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم لَوْ عَلِمْتُ أَنَّ لِي حَيَاةً مَا حَدَّثْتُكَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَا مِنْ عَبْدٍ يَسْتَرْعِيهِ اللَّهُ رَعِيَّةً يَمُوتُ يَوْمَ يَمُوتُ وَهُوَ غَاشٌّ لِرَعِيَّتِهِ إِلاَّ حَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ " .
Shayban ibn Farrukh narrated to us: Abu al-Ashhab narrated to us, from al-Hasan, who said: 'Ubaydullah ibn Ziyad visited Ma'qil ibn Yasar al-Muzani during the illness from which he died. Ma'qil said: I will tell you a hadith I heard from the Messenger of Allah (peace and blessings be upon him). Had I known I would live, I would not have told it to you. I heard the Messenger of Allah (peace and blessings be upon him) say: If Allah entrusts a servant with a community to govern, and he dies while betraying those under his care, Allah will forbid Paradise to him.
