A man said: Messenger of Allah, my mother has died ; will it benefit her if I give sadaqah on her behalf ? He said: Yes. He said: I have a garden, and I call you to witness that I have given it as sadaqah on her behalf. (Using translation from Abū Dāʾūd 2882)
يَا رَسُولَ اللهِ إِنَّ أُمَّهُ تُوُفِّيَتْ أَفَيَنْفَعُهَا إِنْ تَصَدَّقْتُ عَنْهَا؟ فَقَالَ «نَعَمْ» قَالَ فَإِنَّ لِي مَخْرَفًا وَأُشْهِدُكَ أَنِّي قَدْ تَصَدَّقْتُ بِهِ عَنْهَا
