٦ حَدَّثَنِي مُحَمَّدُ بْنُ جَعْفَرٍ الرَّزَّازُ الْكُوفِيُّ الْقُرَشِيُّ عَنْ خَالِهِ مُحَمَّدِ بْنِ الْحُسَيْنِ بْنِ أَبِي الْخَطَّابِ عَمَّنْ حَدَّثَهُ عَنْ عَلِيِّ بْنِ مَيْمُونٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ (ع) يَقُولُ لَوْ أَنَّ أَحَدَكُمْ حَجَّ أَلْفَ حِجَّةٍ ثُمَّ لَمْ يَأْتِ قَبْرَ الْحُسَيْنِ بْنِ عَلِيٍّ (ع) لَكَانَ قَدْ تَرَكَ حَقّاً مِنْ حُقُوقِ اللَّهِ تَعَالَى وَ سُئِلَ عَنْ ذَلِكَ فَقَالَ حَقُّ الْحُسَيْنِ (ع) مَفْرُوضٌ عَلَى كُلِّ مُسْلِمٍ
6. Muĥammad ibn Ja’far Al-Razzāz Al-Kūfi Al-Qurashi narrated to me from his uncle Muĥammad ibn Ĥusain ibn Abil Khaťťāb, from someone who narrated to him, from ‘Ali ibn Maymūn, who said: I heard Abā ‘Abdillāh (Imam Šādiq ) say: Verily if one of you goes for Hajj one thousand times but does not go to (the Ziyārah of) the grave of Ĥusain ibn ‘Ali , he has neglected one of his obligations toward Allāh, the Exalted. Then someone asked the Imam  for the reason and he replied, “Fulfilling one’s obligation toward Ĥusain  is mandatory on every Muslim.”
