١٠ وَ بِهَذَا الْإِسْنَادِ عَنِ الْعَمْرَكِيِّ بْنِ الْبُوفَكِيِّ عَمَّنْ حَدَّثَهُ عَنْ مُحَمَّدِ بْنِ الْفَضْلِ عَنْ أَبِي رَبَابٍ [رِئَابٍ] قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ (ع) عَنْ زِيَارَةِ قَبْرِ الْحُسَيْنِ (ع) قَالَ نَعَمْ تَعْدِلُ عُمْرَةً وَ لَا يَنْبَغِي أَنْ يَتَخَلَّفَ عَنْهُ أَكْثَرَ مِنْ أَرْبَعِ سِنِينَ
10. A group of our companions narrated to me from Aĥmad ibn Idrǐs, and from Muĥammad ibn Yaĥyā Al-‘Aťťār, from ‘Amraki ibn Al-Būfaki, from someone who narrated to him, from Muĥammad ibn Fuďayl, from Abǐ Rabāb, who said: I asked Abā ‘Abdillāh (Imam Šādiq ) about (the reward for) going to the Ziyārah of the grave of Ĥusain . Imam  said, “It is equal to performing an ‘Umrah, and one is not permitted to stay away from it for longer than four years.”
