Narrated `Ali:
حَدَّثَنَا يَسَرَةُ بْنُ صَفْوَانَ ، حَدَّثَنَا إِبْرَاهِيمُ ، عَنْ أَبِيهِ ، عَنْ عَبْدِ اللَّهِ بْنِ شَدَّادٍ ، عَنْ عَلِيٍّ ـ رضى الله عنه ـ قَالَ مَا سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم جَمَعَ أَبَوَيْهِ لأَحَدٍ إِلاَّ لِسَعْدِ بْنِ مَالِكٍ، فَإِنِّي سَمِعْتُهُ يَقُولُ يَوْمَ أُحُدٍ " يَا سَعْدُ ارْمِ، فِدَاكَ أَبِي وَأُمِّي " .
I have never heard the Prophet (ﷺ) mentioning his father and mother for anybody other than Sa`d bin Malik. I heard him saying on the day of Uhud, "O Sa`d throw (arrows)! Let my father and mother be sacrificed for you !"
