(7) باب إِذَا مَاتَ الْفَجْأَةَ هَلْ يُسْتَحَبُّ لأَهْلِهِ أَنْ يَتَصَدَّقُوا عَنْهُ
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.
