فَحَدَّثَنَاهُ أَبُو سَعِيدٍ أَحْمَدُ بْنُ مُحَمَّدٍ النَّسَوِيُّ ثنا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ سَعِيدٍ ثنا أَحْمَدُ بْنُ الْحُسَيْنِ بْنِ عَلِيٍّ حَدَّثَنِي أَبِي عَنْ أَبِيهِ عَنْ جَدِّهِ عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ قَالَ

سُئِلَ رَسُولُ اللَّهِ ﷺ عَنْ مَاءِ الْبَحْرِ فَقَالَ «هُوَ الطَّهُورُ مَاؤُهُ الْحِلُّ مَيْتَتُهُ» «وَأَمَّا حَدِيثُ ابْنِ عَبَّاسٍ فَقَدْ ذَكَرْنَاهُ»
