حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا عَلِيُّ بْنُ ثَابِتٍ، حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ النُّعْمَانِ بْنِ مَعْبَدِ بْنِ هَوْذَةَ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ أَمَرَ بِالإِثْمِدِ الْمُرَوَّحِ عِنْدَ النَّوْمِ وَقَالَ ‏ "‏ لِيَتَّقِهِ الصَّائِمُ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ قَالَ لِي يَحْيَى بْنُ مَعِينٍ هُوَ حَدِيثٌ مُنْكَرٌ يَعْنِي حَدِيثَ الْكَحْلِ ‏.‏
