Sahih al-Bukhari 4057
Narrated Ibn Al Musaiyab:
Sa`d bin Abi Waqqas said, "Allah's Messenger (ﷺ) mentioned both his father and mother for me on the day 
of the battle of Uhud." He meant when the Prophet (ﷺ) said (to Sa`d) while the latter was fighting. "Let 
my father and mother be sacrificed for you!"
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا لَيْثٌ، عَنْ يَحْيَى، عَنِ ابْنِ الْمُسَيَّبِ، أَنَّهُ قَالَ قَالَ سَعْدُ بْنُ أَبِي وَقَّاصٍ ـ رضى الله عنه ـ لَقَدْ جَمَعَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَ أُحُدٍ أَبَوَيْهِ كِلَيْهِمَا‏.‏ يُرِيدُ حِينَ قَالَ ‏
"‏ فِدَاكَ أَبِي وَأُمِّي ‏"‏‏.‏ وَهُوَ يُقَاتِلُ‏.‏
