عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ أَحْمَدَ بْنِ الْمُبَارَكِ عَنِ الْحُسَيْنِ بْنِ الْحَسَنِ بْنِ عَاصِمٍ عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ مَنْ نَامَ عَلَى إِثْمِدٍ غَيْرِ مُمَسَّكٍ أَمِنَ مِنَ الْمَاءِ الْأَسْوَدِ أَبَداً مَا دَامَ يَنَامُ عَلَيْهِ .
9. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from Ahmad ibn Muhammad from ibn abu Nasr from Ahmad ibn al-Mubarak from al-Husayn ibn al-Hassan ibn ‘Asem from his father who has said the following: “Abu ‘Abd Allah , has said, ’If one sleeps with eye powder containing Athmad (antimony) but without musk, he remains immune from Ma’ al-Aswad (a certain eye illness) all the time as long as he sleeps with it.”’
