It was narrated from ‘Abdullah bin Shaddad:
Sa`d bin al-Hadi said: I heard `Ali (رضي الله عنه) say: I never heard the Prophet (ﷺ) mention his father and mother together (in the phrase `may my father and mother be sacrificed for you`) for anyone except Sa’d bin Abi Waqqas. I heard him say on the day of Uhud: `Shoot, O Sa`d, may my father and mother be sacrificed for you!`
