"Sa'd bin 'Ubadah went out with the Prophet on one of his campaigns, and death came to his mother in Al-Madinah. It was said to her (as she was dying): 'Make a will.' She said: 'To whom shall I make a will? The wealth belongs to Sa'd.' Then she died before Sa'd came. When Sa'd came, he was told about that and he said: 'O Messenger of Allah, will it benefit her if I give in charity on her behalf?' The Prophet said: 'Yes.' Sa'd said: 'Such and such a garden is given in charity on her behalf' -regarding a garden that he named." (Using translation from Nasāʾī 3650)
ثنا الْقَعْنَبِيُّ فِيمَا قَرَأَ عَلَى مَالِكٍ عَنْ سَعِيدِ بْنِ عَمْرِو بْنِ شُرَحْبِيلَ بْنِ سَعِيدِ بْنِ عَبَّادٍ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّهُ قَالَ خَرَجَ سَعْدُ بْنُ عُبَادَةَ مَعَ النَّبِيِّ ﷺ فِي بَعْضِ مَغَازِيهِ فَحَضَرَتْ أُمَّ سَعْدٍ الْوَفَاةُ فَقِيلَ لَهَا أَوْصِي قَالَتْ فِيمَا أُوصِي؟ إِنَّمَا الْمَالُ مَالُ سَعْدٍ فَتُوُفِّيَتْ قَبْلَ أَنْ يَقْدَمَ سَعْدٌ فَلَمَّا قَدِمَ سَعْدٌ ذُكِرَ لَهُ ذَلِكَ فَقَالَ يَا رَسُولَ اللَّهِ هَلْ يَنْفَعُهَا أَنْ أَتَصَدَّقَ عَنْهَا؟ قَالَ «نَعَمْ» قَالَ سَعْدٌ حَائِطُ كَذَا وَكَذَا صَدَقَةٌ عَنْهَا الْحَائِطُ قَدْ سَمَّاهُ
