Hadith 4472

Ibn ‘Abbas reported the Prophet as saying, “Apply antimony, for it clears the sight and makes the hair grow.” And he asserted that the Prophet had a collyrium-case from which he applied collyrium every night in each eye three times. Tirmidhi transmitted it.

وَعَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «اكْتَحِلُوا بِالْإِثْمِدِ فَإِنَّهُ يَجْلُو الْبَصَرَ وَيُنْبِتُ الشَّعْرَ» . وَزَعَمَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَتْ لَهُ مُكْحُلَةٌ يَكْتَحِلُ بِهَا كُلَّ لَيْلَةٍ ثَلَاثَةً فِي هَذِهِ وَثَلَاثَةً فِي هَذِه. رَوَاهُ التِّرْمِذِيّ
