خَٰشِعَةً أَبْصَٰرُهُمْ تَرْهَقُهُمْ ذِلَّةٌۭ ۖ وَقَدْ كَانُوا۟ يُدْعَوْنَ إِلَى ٱلسُّجُودِ وَهُمْ سَٰلِمُونَ
With eyes downcast, abasement stupefying them. And they had been summoned to prostrate themselves while they were yet unhurt.

Chapter: Saying "let my father and mother be sacrificed for you".
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.")
