4ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ الله عَنْ عُثْمَانَ بْنِ عِيسَى عَنِ الْمُعَلَّى أَبِي شِهَابٍ قَالَ قَالَ الْحُسَيْنُ (عَلَيْهِ السَّلاَم) لِرَسُولِ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) يَا أَبَتَاهْ مَا لِمَنْ زَارَكَ فَقَالَ رَسُولُ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) يَا بُنَيَّ مَنْ زَارَنِي حَيّاً أَوْ مَيِّتاً أَوْ زَارَ أَبَاكَ أَوْ زَارَ أَخَاكَ أَوْ زَارَكَ كَانَ حَقّاً عَلَيَّ أَنْ أَزُورَهُ يَوْمَ الْقِيَامَةِ وَأُخَلِّصَهُ مِنْ ذُنُوبِهِ.
4. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from ‘Uthman ibn ‘Isa from al-Mu‘alla’ abu Shihab who has said the following: “He (the Imam) (a.s.), has said that al-Husayn (a.s.), once asked, ‘What, O grandfather, is the reward for one who visits you?’ The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, replied as follows: ‘My son, whoever visits me in my lifetime or after I die, or visits your father, your brother or visits you, it becomes necessary for me to visit him on the Day of Judgment to save him from his sins.’”
