"Three will receive their reward twice: A slave who fulfills the rights of Allah and the rights of his owners, then he will be given his reward twice. And a man who has a beautiful slave girl, so he teaches her good manners, then he frees her, then he married her seeking the Face of Allah by that; then he will be given his reward twice. And a man who believed in an earlier Book, then another Book came to him and he believed in it; then he will be given his reward twice."  

رَسُولُ اللَّهِ ﷺ ثَلاَثَةٌ يُؤْتَوْنَ أَجْرَهُمْ مَرَّتَيْنِ عَبْدٌ أَدَّى حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ فَذَلِكَ يُؤْتَى أَجْرَهُ مَرَّتَيْنِ وَرَجُلٌ كَانَتْ عِنْدَهُ جَارِيَةٌ وَضِيئَةٌ فَأَدَّبَهَا فَأَحْسَنَ أَدَبَهَا ثُمَّ أَعْتَقَهَا ثُمَّ تَزَوَّجَهَا يَبْتَغِي بِذَلِكَ وَجْهَ اللَّهِ فَذَلِكَ يُؤْتَى أَجْرَهُ مَرَّتَيْنِ وَرَجُلٌ آمَنَ بِالْكِتَابِ الأَوَّلِ ثُمَّ جَاءَ الْكِتَابُ الآخَرُ فَآمَنَ بِهِ فَذَلِكَ يُؤْتَى أَجْرَهُ مَرَّتَيْنِ حَدَّثَنَا ابْنُ أَبِي عُمَرَ حَدَّثَنَا سُفْيَانُ عَنْ صَالِحِ بْنِ صَالِحٍ وَهُوَ ابْنُ حَىٍّ عَنِ الشَّعْبِيِّ عَنْ أَبِي بُرْدَةَ عَنْ أَبِي مُوسَى عَنِ النَّبِيِّ ﷺ نَحْوَهُ
