Volume 8, Book 73, Number 203:
Narrated ‘Ali:
I never heard Allah’s Apostle saying, “Let my father and mother be sacrificed for you,” except for
Sa’d (bin Abi Waqqas). I heard him saying, “Throw! (arrows), Let my father and mother be sacrificed
for you !” (The sub-narrator added, “I think that was in the battle of Uhud.”)
