1681. It was reported from Abū Ishāq, from a man, from Sa'd bin 'Ubādah, that he said: "O Messenger of Allāh, the mother of Sa'd (my mother) has died, so which type of charity is best (on her behalf)?" He replied: "Water." Sa'd added: "So we dug a well, and said: 'This is for the mother of Sa'd.'" (Da'if)
