الكبرى للنسائي:٨٤٤٠أَخْبَرَنَا هِلَالُ بْنُ الْعَلَاءِ قَالَ حَدَّثَنَا أَبِي قَالَ حَدَّثَنَا عُبَيْدُ اللهِ عَنْ زَيْدِ بْنِ أَبِي أُنَيْسَةَ عَنْ أَبِي إِسْحَاقَ

عَنْ خَالِدِ بْنِ قُثَمَ إِنَّهُ قِيلَ لَهُ مَا لِعَلِيٍّ وَرِثَ رَسُولَ اللهِ ﷺ دُونَ جَدِّكَ وَهُوَ عَمُّهُ؟ قَالَ «إِنَّ عَلِيًّا كَانَ أَوَّلَنَا بِهِ لُحُوقًا وَأَشَدَّنَا بِهِ لُصُوقًا»
