Narrated Buraidah:

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.

حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَطَاءٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، بُرَيْدَةَ : 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 .
