[Machine] The Prophet ﷺ said, "Use al-ithmid, as it clears the vision and promotes hair growth." It is claimed that the Messenger of Allah ﷺ used to have a kohl container with which he would apply kohl three times in one eye and three times in the other eye every night. This is the most authentic narration regarding the kohl application of the Prophet ﷺ.
أَنَّ النَّبِيَّ ﷺ قَالَ عَلَيْكُمْ بِالْإِثْمِدِ فَإِنَّهُ يَجْلُو الْبَصَرَ وَيُنْبِتُ الشَّعْرَ وَزَعَمَ أَنَّ رَسُولَ اللهِ ﷺ كَانَتْ لَهُ مُكْحُلَةٌ يَكْتَحِلُ مِنْهَا كُلَّ لَيْلَةٍ ثَلَاثًا فِي هَذِهِ وَثَلَاثًا فِي هَذِهِ هَذَا أَصَحُّ مَا رُوِيَ فِي اكْتِحَالِ النَّبِيِّ ﷺ
