Narrated Abu Burda's father:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ ، حَدَّثَنَا صَالِحُ بْنُ حَىٍّ أَبُو حَسَنٍ ، قَالَ سَمِعْتُ الشَّعْبِيَّ ، يَقُولُ حَدَّثَنِي أَبُو بُرْدَةَ ، أَنَّهُ سَمِعَ أَبَاهُ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " ثَلاَثَةٌ يُؤْتَوْنَ أَجْرَهُمْ مَرَّتَيْنِ الرَّجُلُ تَكُونُ لَهُ الأَمَةُ فَيُعَلِّمُهَا فَيُحْسِنُ تَعْلِيمَهَا، وَيُؤَدِّبُهَا فَيُحْسِنُ أَدَبَهَا، ثُمَّ يُعْتِقُهَا فَيَتَزَوَّجُهَا، فَلَهُ أَجْرَانِ، وَمُؤْمِنُ أَهْلِ الْكِتَابِ الَّذِي كَانَ مُؤْمِنًا، ثُمَّ آمَنَ بِالنَّبِيِّ صلى الله عليه وسلم فَلَهُ أَجْرَانِ، وَالْعَبْدُ الَّذِي يُؤَدِّي حَقَّ اللَّهِ وَيَنْصَحُ لِسَيِّدِهِ " . ثُمَّ قَالَ الشَّعْبِيُّ وَأَعْطَيْتُكَهَا بِغَيْرِ شَىْءٍ وَقَدْ كَانَ الرَّجُلُ يَرْحَلُ فِي أَهْوَنَ مِنْهَا إِلَى الْمَدِينَةِ.
The Prophet (ﷺ) said, "Three persons will get their reward twice. (One is) a person who has a slave girl and he educates her properly and teaches her good manners properly (without violence) and then manumits and marries her. Such a person will get a double reward. (Another is) a believer from the people of the scriptures who has been a true believer and then he believes in the Prophet (ﷺ) (Muhammad). Such a person will get a double reward. (The third is) a slave who observes Allah's Rights and Obligations and is sincere to his master."
