"O Messenger of Allah, my mother died; will it benefit her if I give in charity on her behalf?" He said: "Yes." He said: "I have a garden and I ask you to bear witness that I am giving it in charity on her behalf." (Using translation from Nasāʾī 3655)
لِرَسُولِ اللَّهِ ﷺ إِنَّ أُمَّهُ تُوُفِّيَتْ أَفَيَنْفَعُهَا إِنْ تَصَدَّقْتُ عَنْهَا؟ قَالَ «نَعَمْ» قَالَ فَإِنَّ لِي مَخْرَفًا وَأُشْهِدُكَ أَنِّي قَدْ تَصَدَّقْتُ عَنْهَا
