حَدَّثَنَا مُحَمَّدُ بْنُ حُمَيْدٍ الرَّازِيُّ، قَالَ: حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ، عَنْ عَبَّادِ بْنِ مَنْصُورٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم، قَالَ: اكْتَحِلُوا بِالإِثْمِدِ، فَإِنَّهُ يَجْلُو الْبَصَرَ، وَيُنْبِتُ الشَّعْرَ وَزَعَمَ أَنَّ النَّبِيَّ صلى الله عليه وسلم، كَانَتْ لَهُ مُكْحُلَةٌ يَكْتَحِلُ مِنْهَا كُلَّ لَيْلَةٍ، ثَلاثَةً فِي هَذِهِ، وَثَلاثَةً فِي هَذِهِ.
