Buraidah said A woman came to the Messenger of Allah ﷺ and said I gave a slave girl as sadaqah to my mother who has now died and has left that slave girl. He said your reward is sure and the inheritance has given her back to you.  

أَنَّ امْرَأَةً أَتَتْ رَسُولَ اللَّهِ ﷺ فَقَالَتْ كُنْتُ تَصَدَّقْتُ عَلَى أُمِّي بِوَلِيدَةٍ وَإِنَّهَا مَاتَتْ وَتَرَكَتْ تِلْكَ الْوَلِيدَةَ قَالَ قَدْ وَجَبَ أَجْرُكِ وَرَجَعَتْ إِلَيْكِ فِي الْمِيرَاثِ  

A woman came to the Prophet ﷺ and said: I gave a slave girl to my mother, but she died and left the salve-girl. He said: Your reward became certain for you, and she (the slave-girl) returned to you as inheritance. She said: She died and one month's fast was due from her. He (the narrator) then mentioned the tradition similar to the one mentioned by 'Amr b. 'Awn.  

أَنَّ امْرَأَةً أَتَتْ رَسُولَ اللَّهِ ﷺ فَقَالَتْ كُنْتُ تَصَدَّقْتُ عَلَى أُمِّي بِوَلِيدَةٍ وَإِنَّهَا مَاتَتْ وَتَرَكَتْ تِلْكَ الْوَلِيدَةَ قَالَ قَدْ وَجَبَ أَجْرُكِ وَرَجَعَتْ إِلَيْكِ فِي الْمِيرَاثِ قَالَتْ وَإِنَّهَا مَاتَتْ وَعَلَيْهَا صَوْمُ شَهْرٍ فَذَكَرَ نَحْوَ حَدِيثِ عَمْرٍو  

“A woman came to-the Prophet ﷺ and said: 'O Messenger of Allah ﷺ, I gave my mother a slave girl of mine, and she has died.' The Messenger of Allah ﷺ said: 'Allah (SWT) has rewarded you, and returned to you your inheritance (without your seeking that.' ”  

جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنِّي تَصَدَّقْتُ عَلَى أُمِّي بِجَارِيَةٍ وَإِنَّهَا مَاتَتْ فَقَالَ آجَرَكِ اللَّهُ وَرَدَّ عَلَيْكِ الْمِيرَاثَ
