I never heard Messenger of Allah ﷺ saying, "Let my father and mother be sacrificed for you," except for Saʿd (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.")  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يُفَدِّي أَحَدًا غَيْرَ سَعْدٍ سَمِعْتُهُ يَقُولُ ارْمِ فَدَاكَ أَبِي وَأُمِّي أَظُنُّهُ يَوْمَ أُحُدٍ  

[Machine] I have never seen the Messenger of Allah ﷺ sacrificing anyone except Saad, for I heard him saying: "O Allah, I sacrifice for you my father and my mother."  

مَا رَأَيْتُ رَسُولَ اللهِ ﷺ يُفَدِّي أَحَدًا غَيْرَ سَعْدٍ فَإِنِّي سَمِعْتُهُ يَقُولُ «ارْمِ فِدَاكَ أَبِي وَأُمِّي»  

[Machine] I have never seen the Prophet ﷺ gather his parents for anyone except for Saad, as he said, "I sacrifice my father and mother for you."  

مَا رَأَيْتُ النَّبِيَّ ﷺ جَمَعَ أَبَوَيْهِ لِأَحَدٍ إِلَّا لِسَعْدٍ فَإِنَّهُ قَالَ «ارْمِ فِدَاكَ أَبِي وَأُمِّي»  

"عَنِ ابْنِ عَبَّاسٍ قَالَ: سَمعْتُ النَّبِىَّ ﷺ (*) جَمَعَ أَبَوَيْهِ لِأَحدٍ إِلا لِسَعْدٍ، فَإِنِّى سَمِعْتُهُ يَقُولُ: ارْمِ سَعْدُ، فدَاكَ أَبِى وَأُمِّى".  

"عَنْ عَلِى قَالَ: مَا سَمِعْتُ رسول الله ﷺ يَفْدِى أحَدًا بِأَبَويْهِ إلَّا سَعْدًا، فإنى سَمِعْتُه يَقولُ يَومَ أُحُدٍ ارْمِ سَعْدُ فِداكَ أَبِى وَأُمِّى".
