Messenger of Allah ﷺ said "Three persons will have a double reward: 1. A Person from the people of the scriptures who believed in his prophet (Jesus or Moses) and then believed in the Prophet ﷺ Muhammad (i .e. has embraced Islam). 2. A slave who discharges his duties to Allah and his master. 3. A master of a woman-slave who teaches her good manners and educates her in the best possible way (the religion) and manumits her and then marries her."  

رَسُولُ اللَّهِ ﷺ: «ثَلاَثَةٌ لَهُمْ أَجْرَانِ: (١) رَجُلٌ مِنْ أَهْلِ الْكِتَابِ آمَنَ بِنَبِيِّهِ وَآمَنَ بِمُحَمَّدٍ ﷺ، (٢) وَالْعَبْدُ الْمَمْلُوكُ إِذَا أَدَّى حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ، (٣) وَرَجُلٌ كَانَتْ عِنْدَهُ أَمَةٌ (يَطَؤُهَا) فَأَدَّبَهَا فَأَحْسَنَ تَأْدِيبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا ثُمَّ أَعْتَقَهَا فَتَزَوَّجَهَا فَلَهُ أَجْرَانِ۔»  

The Prophet ﷺ said, "He who has a slave-girl and teaches her good manners and improves her education and then manumits and marries her, will get a double reward; and any slave who observes Allah's right and his master's right will get a double reward."  

عَنْ أَبِي مُوسَى الأَشْعَرِيِّ ؓ قَالَ النَّبِيُّ ﷺ أَيُّمَا رَجُلٍ كَانَتْ لَهُ جَارِيَةٌ فَأَدَّبَهَا فَأَحْسَنَ تَأْدِيبَهَا وَأَعْتَقَهَا وَتَزَوَّجَهَا فَلَهُ أَجْرَانِ وَأَيُّمَا عَبْدٍ أَدَّى حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ فَلَهُ أَجْرَانِ  

"The Messenger of Allah said: 'There are three who will be given a twofold reward: A man who has a slave woman whom he disciplines and disciplines her well, and teaches and teaches her well, then he manumits her and marries her; a slave who fulfills his duty toward Allah and toward his masters; and a believer from among the People of the Book.'"  

قَالَ رَسُولُ اللَّهِ ﷺ ثَلاَثَةٌ يُؤْتَوْنَ أَجْرَهُمْ مَرَّتَيْنِ رَجُلٌ كَانَتْ لَهُ أَمَةٌ فَأَدَّبَهَا فَأَحْسَنَ أَدَبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا ثُمَّ أَعْتَقَهَا وَتَزَوَّجَهَا وَعَبْدٌ يُؤَدِّي حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ وَمُؤْمِنُ أَهْلِ الْكِتَابِ  

'Whoever has a slave woman and teaches her good manners and educates her, then sets her free and marries her, will have two rewards. Any man from among the People of the Book who believed in his Prophet and believed in Muhammad will have two rewards. Any slave who does his duty towards Allah and towards his masters will have two rewards.” (Sahih)(one of the narrators) Salih said: “Sha'bi said: 'I have given this (Hadith) to you for little effort on your part. A rider would travel to Al-Madinah for less than this.' ”  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ كَانَتْ لَهُ جَارِيَةٌ فَأَدَّبَهَا فَأَحْسَنَ أَدَبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا ثُمَّ أَعْتَقَهَا وَتَزَوَّجَهَا فَلَهُ أَجْرَانِ وَأَيُّمَا رَجُلٍ مِنْ أَهْلِ الْكِتَابِ آمَنَ بِنَبِيِّهِ وَآمَنَ بِمُحَمَّدٍ فَلَهُ أَجْرَانِ وَأَيُّمَا عَبْدٍ مَمْلُوكٍ أَدَّى حَقَّ اللَّهِ عَلَيْهِ وَحَقَّ مَوَالِيهِ فَلَهُ أَجْرَانِ قَالَ صَالِحٌ قَالَ الشَّعْبِيُّ قَدْ أَعْطَيْتُكَهَا بِغَيْرِ شَىْءٍ إِنْ كَانَ الرَّاكِبُ لَيَرْكَبُ فِيمَا دُونَهَا إِلَى الْمَدِينَةِ  

[Machine] On the authority of the Prophet ﷺ , he said: "Whoever has a slave girl and teaches her, and behaves well towards her, and teaches her good manners, and then frees her and marries her, he will have two rewards. And a servant who fulfills the rights of Allah (may He be exalted) and the rights of his slaves, and a man from the people of the Book who believes in what Jesus brought and what Muhammad ﷺ brought, he will have two rewards."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ كَانَتْ لَهُ أَمَةٌ فَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا وَأَدَّبَهَا فَأَحْسَنَ تَأْدِيبَهَا وَأَعْتَقَهَا فَتَزَوَّجَهَا فَلَهُ أَجْرَانِ وَعَبْدٌ أَدَّى حَقَّ اللهِ ﷻ وَحَقَّ مَوَالِيهِ وَرَجُلٌ مِنْ أَهْلِ الْكِتَابِ آمَنَ بِمَا جَاءَ بِهِ عِيسَى وَمَا جَاءَ بِهِ مُحَمَّدٌ ﷺ فَلَهُ أَجْرَانِ  

'Whoever has a slave woman and teaches her good manners and educates her, then sets her free and marries her, will have two rewards. Any man from among the People of the Book who believed in his Prophet and believed in Muhammad will have two rewards. Any slave who does his duty towards Allah and towards his masters will have two rewards.” (Sahih)(one of the narrators) Salih said: “Sha'bi said: 'I have given this (Hadith) to you for little effort on your part. A rider would travel to Al-Madinah for less than this.' ” (Using translation from Ibn Mājah 1956)   

قَالَ رَسُولُ اللهِ ﷺ مَنْكَانَتْ لَهُ جَارِيَةٌ فَأَدَّبَهَا فَأَحْسَنَ أَدَبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا ثُمَّ أَعْتَقَهَا وَتَزَوَّجَهَا فَلَهُ أَجْرَانِ وَأَيُّمَا رَجُلٍ مِنْ أَهْلِ الْكِتَابِ آمَنَ بِنَبِيِّهِ وَآمَنَ بِمُحَمَّدٍ فَلَهُ أَجْرَانِ وَأَيُّمَا عَبْدٍ مَمْلُوكٍ أَدَّى حَقَّ اللهِ ﷻ عَلَيْهِ وَحَقَّ مَوَالِيهِ فَلَهُ أَجْرَانِ  

"The Messenger of Allah said: 'There are three who will be given a twofold reward: A man who has a slave woman whom he disciplines and disciplines her well, and teaches and teaches her well, then he manumits her and marries her; a slave who fulfills his duty toward Allah and toward his masters; and a believer from among the People of the Book.'" (Using translation from Nasāʾī 3344)  

قَالَ رَسُولُ اللهِ ﷺ ثَلَاثَةٌ يُؤْتَوْنَ أَجْرَهُمْ مَرَّتَيْنِ رَجُلٌ كَانَتْ لَهُ أَمَةٌ فَأَدَّبَهَا فَأَحْسَنَ أَدَبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا ثُمَّ أَعْتَقَهَا وَتَزَوَّجَهَا وَعَبْدٌ يُؤَدِّي حَقَّ اللهِ وَحَقَّ مَوَالِيهِ وَمُؤْمِنُ أَهْلِ الْكِتَابِ  

[Machine] The Messenger of Allah ﷺ said: "Whoever has a female slave and treats her well, educates her and teaches her, and then sets her free and marries her, he will have two rewards. And whoever fulfills the rights of Allah and the rights of his slaves, he will have two rewards."  

قَالَ رَسُولُ اللهِ ﷺ أَيُّمَا رَجُلٍ كَانَتْ لَهُ جَارِيَةٌ فَأَدَّبَهَا وَأَحْسَنَ تَأْدِيبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا ثُمَّ أَعْتَقَهَا فَتَزَوَّجَهَا فَلَهُ أَجْرَانِ وَأَيُّمَا عَبْدٍ مَمْلُوكٍ أَدَّى حَقَّ اللهِ ﷻ وَحَقَّ مَوَالِيهِ فَلَهُ أَجْرَانِ  

"ثَلَاثَةٌ يُؤتَوْنَ أَجْرَهُم مرتين: رجل من أَهلِ الكتابِ آمن بنبيه وَأَدرك النبى ﷺ فآمنَ به واتبعه وصدَّقه فله أجران، وعبد مملوك أدَّى حقَّ اللَّه وحقَّ سيِّدِه فله أَجْران، ورجل كانت له أَمةٌ فَغَذَّاها فأحسَنَ عداءَها ثُمَّ أَدَّبها فأحسن تأدِيبها وعلَّمها فأَحسنَ تعليمها ثم أعتقها وتزوجها فلَه أَجران".
