I have never heard the Prophet ﷺ mentioning his father and mother for anybody other than Saʿd bin Malik. I heard him saying on the day of Uhud, "O Saʿd throw (arrows)! Let my father and mother be sacrificed for you !"  

سَمِعْتُ النَّبِيَّ ﷺ جَمَعَ أَبَوَيْهِ لأَحَدٍ إِلاَّ لِسَعْدِ بْنِ مَالِكٍ فَإِنِّي سَمِعْتُهُ يَقُولُ يَوْمَ أُحُدٍ يَا سَعْدُ ارْمِ فِدَاكَ أَبِي وَأُمِّي  

Saʿd bin al-Hadi said: I heard ʿAli ؓ say: I never heard the Prophet ﷺ mention his father and mother together (in the phrase ʿmay my father and mother be sacrificed for youʿ) for anyone except Sa’d bin Abi Waqqas. I heard him say on the day of Uhud: ʿShoot, O Saʿd, may my father and mother be sacrificed for you!ʿ  

سَمِعْتُ النَّبِيَّ ﷺ يَجْمَعُ أَبَاهُ وَأُمَّهُ لِأَحَدٍ غَيْرَ سَعْدِ بْنِ أَبِي وَقَّاصٍ فَإِنِّي سَمِعْتُهُ يَقُولُ يَوْمَ أُحُدٍ ارْمِ يَا سَعْدُ فِدَاكَ أَبِي وَأُمِّي  

I never heard the Messenger of Allah ﷺ say ʿMay my father and mother be sacrificed for you.ʿ to anyone except Saʿd bin Malik, I heard him say to him on the day of Uhud. “Shoot, Saʿd, may my father and mother be sacrificed for you!ʿ  

سَمِعْتُ رَسُولَ اللهِ ﷺ يُفَدِّي أَحَدًا بِأَبَوَيْهِ إِلا سَعْدَ بْنَ مَالِكٍ فَإِنِّي سَمِعْتُهُ يَقُولُ لَهُ يَوْمَ أُحُدٍ ارْمِ سَعْدُ فِدَاكَ أَبِي وَأُمِّي  

[Machine] I heard the Prophet ﷺ gathered both of his parents for someone except for Saad, as he said to him on the day of Uhud: "May my father and mother be sacrificed for you."  

سَمِعْتُ النَّبِيَّ ﷺ جَمَعَ أَبَوَيْهِ لِأَحَدٍ إِلَّا لِسَعْدٍ فَإِنَّهُ قَالَ لَهُ يَوْمَ أُحُدٍ «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".
