"When a man dies all his good deeds come to an end except three: Ongoing charity (Sadaqah Jariyah), beneficial knowledge and a righteous son who prays for him."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا مَاتَ الإِنْسَانُ انْقَطَعَ عَمَلُهُ إِلاَّ مِنْ ثَلاَثَةٍ مِنْ صَدَقَةٍ جَارِيَةٍ وَعِلْمٍ يُنْتَفَعُ بِهِ وَوَلَدٍ صَالِحٍ يَدْعُو لَهُ  

"My father died and left behind wealth, but he did not leave a will. Will it expiate for him if I give charity on his behalf?"  

لِلنَّبِيِّ ﷺ إِنَّ أَبِي مَاتَ وَتَرَكَ مَالاً وَلَمْ يُوصِ فَهَلْ يُكَفِّرُ عَنْهُ أَنْ أَتَصَدَّقَ عَنْهُ قَالَ نَعَمْ  

"I came to the Messenger of Allah and said: 'My mother left a will saying that a slave should be freed on her behalf. I have a Nubian slave girl; will it suffice if I free her on her behalf?' He said: 'Bring her here.' The Prophet said to her: 'Who is your Lord?' She said: 'Allah.' He said: 'Who am I?' She said: 'The Messenger of Allah.' He said: 'Set her free , for she is a believer.'"  

أَتَيْتُ رَسُولَ اللَّهِ ﷺ فَقُلْتُ إِنَّ أُمِّي أَوْصَتْ أَنْ تُعْتَقَ عَنْهَا رَقَبَةٌ وَإِنَّ عِنْدِي جَارِيَةً نُوبِيَّةً أَفَيُجْزِئُ عَنِّي أَنْ أَعْتِقَهَا عَنْهَا قَالَ ائْتِنِي بِهَا فَأَتَيْتُهُ بِهَا فَقَالَ لَهَا النَّبِيُّ ﷺ مَنْ رَبُّكِ قَالَتِ اللَّهُ قَالَ مَنْ أَنَا قَالَتْ أَنْتَ رَسُولُ اللَّهِ قَالَ فَأَعْتِقْهَا فَإِنَّهَا مُؤْمِنَةٌ  

"My mother died and did not leave a will; shall I give charity on her behalf?" He said: "Yes."  

أَنَّ سَعْدًا سَأَلَ النَّبِيَّ ﷺ إِنَّ أُمِّي مَاتَتْ وَلَمْ تُوصِ أَفَأَتَصَدَّقُ عَنْهَا قَالَ نَعَمْ  

"O Messenger of Allah, my mother died; will it benefit her if I give in charity on her behalf?" He said: "Yes." He said: "I have a garden and I ask you to bear witness that I am giving it in charity on her behalf."  

يَا رَسُولَ اللَّهِ إِنَّ أُمَّهُ تُوُفِّيَتْ أَفَيَنْفَعُهَا إِنْ تَصَدَّقْتُ عَنْهَا قَالَ نَعَمْ قَالَ فَإِنَّ لِي مَخْرَفًا فَأُشْهِدُكَ أَنِّي قَدْ تَصَدَّقْتُ بِهِ عَنْهَا  

"My mother has died and she had a vow to fulfill. Will it suffice if I free a slave on her behalf?" He said: "Free a slave on behalf of your mother."  

أَنَّهُ أَتَى النَّبِيَّ ﷺ فَقَالَ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا نَذْرٌ أَفَيُجْزِئُ عَنْهَا أَنْ أَعْتِقَ عَنْهَا قَالَ أَعْتِقْ عَنْ أُمِّكَ  

"Fulfill it on her behalf."  

أَنَّهُ اسْتَفْتَى النَّبِيَّ ﷺ فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَتُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ اقْضِهِ عَنْهَا  

"Fulfill it on her behalf."  

أَنَّهُ اسْتَفْتَى النَّبِيَّ ﷺ فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَمَاتَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ اقْضِهِ عَنْهَا  

"Sa'd consulted the Messenger of Allah about a vow which his mother had to fulfill, but she died before doing so. The Messenger of Allah said: 'Fulfill it on her behalf.'"  

اسْتَفْتَى سَعْدٌ رَسُولَ اللَّهِ ﷺ فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَتُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ اقْضِهِ عَنْهَا
