Sahih
حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَطَاءٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، بُرَيْدَةَ أَنَّ امْرَأَةً، أَتَتْ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَتْ كُنْتُ تَصَدَّقْتُ عَلَى أُمِّي بِوَلِيدَةٍ وَإِنَّهَا مَاتَتْ وَتَرَكَتْ تِلْكَ الْوَلِيدَةَ . قَالَ " قَدْ وَجَبَ أَجْرُكِ وَرَجَعَتْ إِلَيْكِ فِي الْمِيرَاثِ " .
Buraidah said A woman came to the Messenger of Allah (SAWS) 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
