(103) باب قَوْلِ الرَّجُلِ فَدَاكَ أَبِي وَأُمِّي
Narrated `Ali:
I never heard Allah's Messenger (ﷺ) 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.")
