Al-Adab Al-Mufrad #161
Being a master
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنَا حَجَّاجُ بْنُ مِنْهَالٍ، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ عَلِيِّ بْنِ زَيْدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيِّبِ، وَحَمَّادٍ، عَنْ حَبِيبٍ، وَحُمَيْدٍ، عَنِ الْحَسَنِ أَنَّ رَجُلاً أَمَرَ غُلاَمًا لَهُ أَنْ يَسْنُوَ عَلَى بَعِيرٍ لَهُ، فَنَامَ الْغُلاَمُ، فَجَاءَ بِشُعْلَةٍ مِنْ نَارٍ فَأَلْقَاهَا فِي وَجْهِهِ، فَتَرَدَّى الْغُلاَمُ فِي بِئْرٍ، فَلَمَّا أَصْبَحَ أَتَى عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ، فَرَأَى الَّذِي فِي وَجْهِهِ، فَأَعْتَقَهُ.
Al-Hasan reported that a man ordered one of his slaves to draw
water using one of his camels and the man fell asleep. The master came
with a torch and put it in his face and the slave fell into the well. In
the morning, the slave went to 'Umar ibn al-Khattab and 'Umar saw what
had happened to his slave and therefore 'Umar set him free."
