4 وَ عَنْهُ عَنْ سَعْدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ الْعَبَّاسِ بْنِ مُوسَى الْوَرَّاقِ عَنْ يُونُسَ عَنْ عِيسَى بْنِ سُلَيْمَانَ عَنْ مُحَمَّدِ بْنِ زِيَادٍ عَنْ عَمَّتِهِ قُلْتُ سَمِعْتُ أَبَا عَبْدِ اللَّهِ (ع) يَقُولُ إِنَّ فِي طِينِ الْحَائِرِ الَّذِي فِيهِ الْحُسَيْنُ (ع) شِفَاءً مِنْ كُلِّ دَاءٍ وَ أَمَاناً مِنْ كُلِّ خَوْفٍ
4. My father narrated to me from Sa’d, from Aḥmad ibn Muḥammad ibn ‘Isā, from ‘Abbās ibn Mūsā Al-Warrāq, from Yūnus, from ‘Isā ibn Sulaymān, from Muḥammad ibn Ziyād, from his aunt, who said: I heard Abā ‘Abdillāh (Imam Sādiq ) say: Verily the clay of the Ḥā`ir, where Ḥusain is buried, is the cure for every disease and it is protection against any fear.
