البيهقي:٣قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ وَرَوَى عَبْدُ الْعَزِيزِ بْنُ عُمَرَ عَنْ سَعِيدِ بْنِ ثَوْبَانَ عَنْ أَبِي هِنْدَ الْفِرَاسِيِّ عَنْ أَبِي هُرَيْرَةَ

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ لَمْ يُطَهِّرْهُ الْبَحْرُ فَلَا طَهَّرَهُ اللهُ أَنْبَأَهُ أَبُو حَازِمٍ عُمَرُ بْنُ أَحْمَدَ بْنِ إِبْرَاهِيمَ الْحَافِظُ أنبأ أَبُو أَحْمَدَ الْحَافِظُ ثنا أَبُو عَبْدِ اللهِ الْحُسَيْنُ بْنُ مُحَمَّدِ بْنِ عُفَيْرٍ الْأَنْصَارِيُّ ثنا مُحَمَّدُ بْنُ حُمَيْدٍ ثنا إِبْرَاهِيمُ بْنُ الْمُخْتَارِ ثنا عَبْدُ الْعَزِيزِ بْنُ عُمَرَ فَذَكَرَهُ بِمِثْلِهِ إِلَّا أَنَّهُ لَمْ يَقُلِ الْفِرَاسِيَّ
