It was narrated from 'Aishah that a man said to the Messenger of Allah:

"My mother died unexpectedly; if she had been able to speak she would have given charity. Should I give charity on her behalf?" The Messenger of Allah said: "Yes." So he gave charity on her behalf.

أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، قَالَ حَدَّثَنَا ابْنُ الْقَاسِمِ، عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ رَجُلاً، قَالَ لِرَسُولِ اللَّهِ ﷺ إِنَّ أُمِّي افْتُلِتَتْ نَفْسُهَا وَإِنَّهَا لَوْ تَكَلَّمَتْ تَصَدَّقَتْ أَفَأَتَصَدَّقُ عَنْهَا فَقَالَ رَسُولُ اللَّهِ ﷺ " نَعَمْ ". فَتَصَدَّقَ عَنْهَا.
