15 وَ قَالَ الْعَمْرَكِيُّ بِإِسْنَادِهِ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ (ع) إِنَّهُ يُصَلِّي عِنْدَ قَبْرِ الْحُسَيْنِ (ع) أَرْبَعَةُ آلَافِ مَلَكٍ- مِنْ طُلُوعِ الْفَجْرِ إِلَى أَنْ تَغِيبَ الشَّمْسُ ثُمَّ يَصْعَدُونَ وَ يَنْزِلُ مِثْلُهُمْ فَيُصَلُّونَ إِلَى طُلُوعِ الْفَجْرِ فَلَا يَنْبَغِي لِلْمُسْلِمِ أَنْ يَتَخَلَّفَ عَنْ زِيَارَةِ قَبْرِهِ أَكْثَرَ مِنْ أَرْبَعِ سِنِينَ
15. ‘Amraki (ibn ‘Ali) narrated through his Isnād that: Abū ‘Abdillāh (Imam Sādiq (a.s.)) said: Verily four thousand angels establish prayers next to the grave of Ḥusain (a.s.) (everyday) from dawn to dusk. Thereafter, they ascend (to the heavens) and are replaced by an equal number of angels who establish prayers (next to his grave from dusk) until dawn. A Muslim should not refrain from (going to) the Ziyārah of his grave for longer than four years.
