Sahih Muslim 142 a
Hasan reported:
'Ubaidullah b. Ziyad paid a visit to Ma'qil b. Yasar Muzani in his illness of which he (later on) died. (At this juncture) Ma'qil said: I am going to narrate to you a hadith which I have heard from the Messenger of Allah (ﷺ) and which I would not have transmitted if I knew that I would survive. Verily I have heard the Messenger of Allah (ﷺ) say: There is none amongst the bondsmen who was entrusted with the affairs of his subjects and he died in such a state that he was dishonest in his dealings with those over whom he ruled except that Paradise is forbidden for him.
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 ‏"‏ ‏.‏
