3 حَدَّثَنِي أَبِي (رحمه الله) وَ جَمَاعَةُ مَشَايِخِي عَنْ سَعْدِ بْنِ عَبْدِ اللَّهِ عَنِ الْحُسَيْنِ بْنِ عَبْدِ اللَّهِ عَنِ الْحَسَنِ بْنِ عَلِيِّ بْنِ أَبِي عُثْمَانَ عَنْ مُحَمَّدِ بْنِ الْفُضَيْلِ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ مَا بَيْنَ قَبْرِ الْحُسَيْنِ (ع) إِلَى السَّمَاءِ مُخْتَلَفُ الْمَلَائِكَةِ
3. My father and all of my scholars narrated to me from Sa’d ibn ‘Abdillāh, from Ḥusain ibn ‘Abdillāh, from Ḥasan ibn ‘Ali ibn Abī ‘Uthmān, from Muḥammad ibn Fuďayl, from Isḥāq ibn ‘Ammār, who said: Abū ‘Abdillāh (Imam Sādiq عليه السلام) said: The space between the grave of Ḥusain عليه السلام and the heavens is (always) filled with angels who are descending and ascending (back and forth from the Ziyārah).
