Sahih Muslim , Book 1, Hadith 271 (In-Book) ⓘ

Hasan reported: Ubaidullah b. Ziyad went to see Ma'qil b. Yasir and he was ailing. He ('Ubaidullah) inquired (about his health) to which he (Ma'qil) replied: I am narrating to you a hadith which I avoided narrating to you (before). Verily the Messenger of Allah observed: Allah does not entrust to his bondsman the responsibility of managing the affairs of his subjects and he dies as a dishonest (ruler) but Paradise is forbidden by Allah for such a (ruler). He (Ibn Ziyad) said: Why did you not narrate it to me before this day? He replied: I (in fact) did not narrate it to you as it was not (fit) for me to narrate that to you.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، قَالَ دَخَلَ عُبَيْدُ اللَّهِ بْنُ زِيَادٍ عَلَى مَعْقِلِ بْنِ يَسَارٍ وَهُوَ وَجِعٌ فَسَأَلَهُ فَقَالَ إِنِّي مُحَدِّثُكَ حَدِيثًا لَمْ أَكُنْ حَدَّثْتُكَهُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يَسْتَرْعِي اللَّهُ عَبْدًا رَعِيَّةً يَمُوتُ حِينَ يَمُوتُ وَهُوَ غَاشٌّ لَهَا إِلاَّ حَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ ‏" ‏ ‏.‏ قَالَ أَلاَّ كُنْتَ حَدَّثْتَنِي هَذَا قَبْلَ الْيَوْمِ قَالَ مَا حَدَّثْتُكَ أَوْ لَمْ أَكُنْ لأُحَدِّثَكَ ‏.‏
