4ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَبَانٍ عَمَّنْ أَخْبَرَهُ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ إِذَا اشْتَكَى الْمُحْرِمُ عَيْنَيْهِ فَلْيَكْتَحِلْ بِكُحْلٍ لَيْسَ فِيهِ مِسْكٌ وَلا طِيبٌ.
4. Al-Husayn ibn Muhammad has narrated from Mu‘alla’ ibn Muhammad from al-Hassan ibn Ali from Aban from those who narrated to him who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘If one in the state of Ihram suffers from illness in the eyes it is permissible for one to use kohl which does not have musk or perfume in it.’”
