 حَدَّثَنِی مُحَمَّدُ بْنُ الْحَسَنِ قَالَ حَدَّثَنِی الْحُسَیْنُ بْنُ الْحَسَنِ بْنِ أَبَانٍ عَنِ الْحُسَیْنِ بْنِ سَعِیدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ إِسْحَاقَ بْنِ إِبْرَاهِیمَ عَنْ هَارُونَ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ ع یَقُولُ وَکَّلَ اللَّهُ بِقَبْرِ الْحُسَیْنِ ع أَرْبَعَهَ آلَافِ مَلَکٍ شُعْثٍ غُبْرٍ یَبْکُونَهُ إِلَی یَوْمِ الْقِیَامَهِ فَمَنْ زَارَهُ عَارِفاً بِحَقِّهِ شَیَّعُوهُ حَتَّی یُبْلِغُوهُ مَأْمَنَهُ وَ إِنْ مَرِضَ عَادُوهُ غُدْوَهً وَ عَشِیّاً وَ إِنْ مَاتَ شَهِدُوا جِنَازَتَهُ وَ اسْتَغْفَرُوا لَهُ إِلَی یَوْمِ الْقِیَامَهِ.
17.  Imam Ja’far Sadiq  says, “The Almighty Allah has appointed four thousand angels at the grave of Imam Husain .  They  will  mourn  over  Imam    with  their  hair covered  in  dust  and  in  a  distressed  state  till  the  Day  of Judgment. One  who goes  for  the  Ziyarat of Imam  Husain   knowing  his  right,  angels  will  go  with  him  till  he returns to his homeland. If he falls ill they would treat him day  and  night.  If  he  dies  they  would  attend  his  funeral prayer and repent for him till the Day of Judgment.”
