حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ كَانَ يُجْنِبُ ثُمَّ يَنَامُ كَهَيْئَتِهِ لاَ يَمَسُّ مَاءً ‏.‏ قَالَ سُفْيَانُ فَذَكَرْتُ الْحَدِيثَ يَوْمًا فَقَالَ لِي إِسْمَاعِيلُ يَا فَتًى يُشَدُّ هَذَا الْحَدِيثُ بِشَىْءٍ ‏.‏
