31) باب تَعْلِيمِ الرَّجُلِ أَمَتَهُ وَأَهْلَهُ

أَخْبَرَنَا مُحَمَّدٌ ـ هُوَ ابْنُ سَلاَمٍ ـ حَدَّثَنَا الْمُحَارِبِيُّ، قَالَ حَدَّثَنَا صَالِحُ بْنُ حَيَّانَ، قَالَ قَالَ عَامِرٌ الشَّعْبِيُّ حَدَّثَنِي أَبُو بُرْدَةَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏‏.‏
ثُمَّ قَالَ عَامِرٌ أَعْطَيْنَاكَهَا بِغَيْرِ شَىْءٍ، قَدْ كَانَ يُرْكَبُ فِيمَا دُونَهَا إِلَى الْمَدِينَةِ‏.‏ "‏ ثَلاَثَةٌ لَهُمْ أَجْرَانِ رَجُلٌ مِنْ أَهْلِ الْكِتَابِ آمَنَ بِنَبِيِّهِ، وَآمَنَ بِمُحَمَّدٍ صلى الله عليه وسلم وَالْعَبْدُ الْمَمْلُوكُ إِذَا أَدَّى حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ، وَرَجُلٌ كَانَتْ عِنْدَهُ أَمَةٌ ‏{‏يَطَؤُهَا‏}‏ فَأَدَّبَهَا، فَأَحْسَنَ تَأْدِيبَهَا، وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا، ثُمَّ أَعْتَقَهَا فَتَزَوَّجَهَا، فَلَهُ أَجْرَانِ ‏"
