مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ الْحَسَنِ بْنِ الْجَهْمِ قَالَ أَرَانِي أَبُو الْحَسَنِ ( عليه السلام ) مِيلًا مِنْ حَدِيدٍ وَ مُكْحُلَةً مِنْ عِظَامٍ فَقَالَ هَذَا كَانَ لِأَبِي الْحَسَنِ فَاكْتَحِلْ بِهِ فَاكْتَحَلْتُ .
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from al-Hassan ibn al-Jahm who has said the following: “Abu al-Hassan , once showed me a pin made of iron and a powder container of bones and said that this belonged to abu al-Hassan with which he applied eye powder and I also apply eye powder to my eyes.’”
