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, "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."  

عَنِ النَّبِيِّ ﷺ 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 ﷺ فَلَهُ أَجْرَانِ وَالْعَبْدُ الَّذِي يُؤَدِّي حَقَّ اللَّهِ وَيَنْصَحُ لِسَيِّدِهِ ثُمَّ قَالَ الشَّعْبِيُّ وَأَعْطَيْتُكَهَا بِغَيْرِ شَىْءٍ وَقَدْ كَانَ الرَّجُلُ يَرْحَلُ فِي أَهْوَنَ مِنْهَا إِلَى الْمَدِينَةِ  

Messenger of Allah ﷺ said, any man who has a slave girl whom he educates properly, teaches good manners, manumits and marries her, will get a double reward And if any man of the people of the Scriptures believes in his own prophet and then believes in me too, he will (also) get a double reward And any slave who fulfills his duty to his master and to his Lord, will (also) get a double reward."  

قَالَ رَسُولُ اللَّهِ ﷺ أَيُّمَا رَجُلٍ كَانَتْ عِنْدَهُ وَلِيدَةٌ فَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا وَأَدَّبَهَا فَأَحْسَنَ تَأْدِيبَهَا ثُمَّ أَعْتَقَهَا وَتَزَوَّجَهَا فَلَهُ أَجْرَانِ وَأَيُّمَا رَجُلٍ مِنْ أَهْلِ الْكِتَابِ آمَنَ بِنَبِيِّهِ وَآمَنَ بِي فَلَهُ أَجْرَانِ وَأَيُّمَا مَمْلُوكٍ أَدَّى حَقَّ مَوَالِيهِ وَحَقَّ رَبِّهِ فَلَهُ أَجْرَانِ قَالَ الشَّعْبِيُّ خُذْهَا بِغَيْرِ شَىْءٍ قَدْ كَانَ الرَّجُلُ يَرْحَلُ فِيمَا دُونَهُ إِلَى الْمَدِينَةِ وَقَالَ أَبُو بَكْرٍ عَنْ أَبِي حَصِينٍ عَنْ أَبِي بُرْدَةَ عَنْ أَبِيهِ عَنِ النَّبِيِّ ﷺ أَعْتَقَهَا ثُمَّ أَصْدَقَهَا  

"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  

[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  

[Machine] The Messenger of Allah ﷺ said: "Whoever has a slave woman, and he educates her well and teaches her well, and then he frees her and marries her, he will have two rewards. And whichever slave performs the rights of Allah and the rights of his master, he will have two rewards."  

قَالَ رَسُولُ اللهِ ﷺ أَيُّمَا رَجُلٍ كَانَتْ لَهُ جَارِيَةٌ فَأَدَّبَهَا فَأَحْسَنَ تَأْدِيبَهَا وَعَلَّمَهَا فَأَحْسَنَ تَعْلِيمَهَا وَأَعْتَقَهَا وَتَزَوَّجَهَا؛ فَلَهُ أَجْرَانِ وَأَيُّمَا عَبْدٍ مَمْلُوكٍ أَدَّى حَقَّ اللهِ 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".
