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
