I heard ‘Abdullah bin Shaddad say: ʿAli ؓ said: I never saw the Messenger of Allah ﷺ mention both of his parents for anyone except Saʿd bin Malik ؓ . On the day of Uhud he started saying: ʿShoot, may my father and mother be sacrificed for you!” (Using translation from Aḥmad 1147)
مَا رَأَيْتُ رَسُولَ اللهِ ﷺ جَمَعَ أَبَوَيْهِ لِأَحَدٍ غَيْرِهِ يَعْنِي سَعْدًا فَإِنَّهُ قَالَ لَهُ يَوْمَ أُحُدٍ «ارْمِ فِدَاكَ أَبِي وَأُمِّي»
