A woman came to the Messenger of Allah ﷺ and said: I donated my slave-girl to my mother, but she died and left the slave-girl. He said: Your reward became due, and she came back to you in inheritance. She said: She died while a month's fasting was due from her. Would it be sufficient or be taken as completed if I fast on her behalf ? He said: Yes. She said: She also did not perform Hajj. Would it be sufficient or be taken completed if I perform (Hajj) on her behalf ? He said: Yes.  

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 أَفَيُجْزِئُ أَوْ يَقْضِي عَنْهَا أَنْ أَصُومَ عَنْهَا قَالَ نَعَمْ قَالَتْ وَإِنَّهَا لَمْ تَحُجَّ أَفَيُجْزِئُ أَوْ يَقْضِي عَنْهَا أَنْ أَحُجَّ عَنْهَا قَالَ نَعَمْ  

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  

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. (Using translation from Abū Dāʾūd 1656)  

أَنَّ امْرَأَةً أَتَتْ رَسُولَ اللهِ ﷺ فَقَالَتْ إِنِّي كُنْتُ تَصَدَّقْتُ عَلَى أُمِّي بِوَلِيدَةٍ وَإِنَّهَا مَاتَتْ وَتَرَكَتْ تِلْكَ الْوَلِيدَةَ فَقَالَ «وَجَبَ أَجْرُكِ وَرَجَعَتْ إِلَيْكِ فِي الْمِيرَاثِ»  

[Machine] I was with the Prophet ﷺ when a woman came to him and said, "O Messenger of Allah, I had made a vow to provide financial support for my mother until my mother passed away, and now my mother has died but the person I made the vow for is still alive." The Prophet ﷺ said, "You have fulfilled your vow, and the person should return to you in terms of inheritance." She said, "But she died while owing a month of fasting." He said, "Then I will fast on behalf of your mother." She said, "But she died without performing the Hajj pilgrimage." He said, "Then I will perform the Hajj pilgrimage on behalf of your mother."  

كُنْتُ عِنْدَ النَّبِيِّ ﷺ فَأَتَتْهُ امْرَأَةٌ فَقَالَتْ يَا رَسُولَ اللهِ إِنِّي كُنْتُ تَصَدَّقْتُ بِوَلِيدَةٍ عَلَى أُمِّي فَمَاتَتْ أُمِّي وَبَقِيَتِ الْوَلِيدَةُ قَالَ قَدْ وَجَبَ أَجْرُكِ وَرَجَعَتْ إِلَيْكِ فِي الْمِيرَاثِ قَالَتْ فَإِنَّهَا مَاتَتْ وَعَلَيْهَا صَوْمُ شَهْرٍ قَالَ صُوْمِي عَنْ أُمِّكِ قَالَتْ وَإِنَّهَا مَاتَتْ وَلَمْ تَحُجَّ قَالَ فَحُجِّي عَنْ أُمُّكِ
