It was narrated from Saeed bin ‘Amr bin Shurahbil bin Saeed bin Saad bin ‘Ubadah, from his father, that his grandfather said: “Sajd bin ‘Ubadah went out with the Prophet صلی اللہ علیہ وآلہ وسلم on one of his campaigns, and death came to his mother in Al Madinah. It was said to her (as she was dying): ‘Make a will.’ She said: ‘To whom shall I make a will? The wealth belongs to Saad.’ Then she died before Saad came. When Saad came, he was told about that and he Said: Messenger of Allah, will it benefit her if I give in charity on her behalf? The Prophet صلی اللہ علیہ وآلہ وسلم said: ‘Yes.’ Saad said: ‘Such and such a garden is given in charity on her behalf’ — regarding a garden that he named.”(Sahih)
