Ibn 'Abbas reported that the Prophet (ﷺ) said (ﷺ):

"Color the edges of the eyelids with antimony [ithmid], for it clears the vision and makes the eyelashes grow!” He also maintained that the Prophet (ﷺ) had a kohl jar from which he used to apply kohl to his eyelashes every night, three times in this [eye],and three times in that.

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.‏
