Narrated Aisha, Ummul Mu'minin:

A woman said: Messenger of Allah, my mother suddenly died; if it had not happened, she would have given sadaqah (charity) and donated (something). Will it suffice if I give sadaqah on her behalf? The Prophet ﷺ said: Yes, give sadaqah on her behalf.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ امْرَأَةً، قَالَتْ يَا رَسُولَ اللَّهِ إِنَّ أُمِّيَ افْتُلِتَتْ نَفْسُهَا وَلَوْلاَ ذَلِكَ لَتَصَدَّقَتْ وَأَعْطَتْ أَفَيُجْزِئُ أَنْ أَتَصَدَّقَ عَنْهَا فَقَالَ النَّبِيُّ ﷺ
" نَعَمْ فَتَصَدَّقِي عَنْهَا " .
