"Indeed the best of what you treat is As-Sa'ut, Al-Ladud, cupping and laxatives.' And the best of what you use for Kuhl is Ithmid, for it clears the vision and grows the hair (eye-lashes)." And he said:" The Messenger of Allah ﷺ had a Kuhl holder with which he would apply Kuhl before sleeping three in each eye."
قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ خَيْرَ مَا تَدَاوَيْتُمْ بِهِ اللَّدُودُ وَالسَّعُوطُ وَالْحِجَامَةُ وَالْمَشِيُّ وَخَيْرُ مَا اكْتَحَلْتُمْ بِهِ الإِثْمِدُ فَإِنَّهُ يَجْلُو الْبَصَرَ وَيُنْبِتُ الشَّعْرَ قَالَ وَكَانَ لِرَسُولِ اللَّهِ ﷺ مُكْحُلَةٌ يَكْتَحِلُ بِهَا عِنْدَ النَّوْمِ ثَلاَثًا فِي كُلِّ عَيْنٍ
