حَدَّثَنَا مَنْصُورُ بْنُ أَبِي مُزَاحِمٍ، حَدَّثَنَا إِبْرَاهِيمُ، - يَعْنِي ابْنَ سَعْدٍ - عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ شَدَّادٍ، قَالَ سَمِعْتُ عَلِيًّا، يَقُولُ مَا جَمَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَبَوَيْهِ لأَحَدٍ غَيْرَ سَعْدِ بْنِ مَالِكٍ فَإِنَّهُ جَعَلَ يَقُولُ لَهُ يَوْمَ أُحُدٍ ‏"‏ ارْمِ فِدَاكَ أَبِي وَأُمِّي ‏"‏ ‏.‏
