Sahih Muslim Book - 1, Hadith - 364

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ عَنْ يُونُسَ عَنْ الْحَسَنِ قَالَ دَخَلَ عُبَيْدُ اللَّهِ بْنُ زِيَادٍ عَلَى مَعْقَلِ بْنِ يَسَارٍ وَهُوَ وَجِعٌ فَسَأَلَهُ فَقَالَ إِنِّي مُحَدِّثُكَ حَدِيثًا لَمْ أَكُنْ حَدَّثْتُكَهُ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَسْتَرْعِي اللَّهُ عَبْدًا رَعِيَّةً يَمُوتُ حِينَ يَمُوتُ وَهُوَ غَاشٌّ لَهَا إِلَّا حَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ.قَالَ أَلَّا كُنْتَ حَدَّثْتَنِي هَذَا قَبْلَ الْيَوْمِ؟ قَالَ مَا حَدَّثْتُكَ أَوْ لَمْ أَكُنْ لَأُحَدِّثَكَ.

It was narrated that Al-Hasan said: "'Ubaidullah bin Ziyad entered upon Ma'qil bin Yasar when he was in pain. He asked him and he said: 'I am going to tell you a Hadith which I did not tell you before. The Messenger of Allah (s.a.w) said: "There is no person whom Allah puts in charge of others, and when he dies he has cheated his subjects, but Allah will forbid Paradise to him."'
