الكبرى للنسائي:٢٦٨٤أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ قَالَ حَدَّثَنَا أَبُو دَاوُدَ عَنْ سُفْيَانَ عَنْ مَنْصُورٍ عَنْ خَالِدِ بْنِ سَعْدٍ عَنْ عَائِشَةَ قَالَتْ

كَانَ رَسُولُ اللهِ ﷺ «يَتَحَرَّى الِاثْنَيْنِ وَالْخَمِيسَ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا حَدِيثٌ مُنْكَرٌ مَا يُشْبِهُ حَدِيثَ مَنْصُورٍ يُشْبِهُ أَنْ يَكُونَ أَتَى مِنْ أَبِي دَاوُدَ
