Chapter 98 | The Minimum Number of Times One Should Go to the Ziyārah of Ĥusain and the Longest Time Allowed to Delay the Ziyārah for the Wealthy and Poor
16 وَ بِإِسْنَادِهِ عَنْ مُحَمَّدِ بْنِ الْفَضْلِ عَنْ أَبِي نَابٍ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ سَأَلْتُهُ عَنْ زِيَارَةِ قَبْرِ الْحُسَيْنِ (ص) قَالَ نَعَمْ تَعْدِلُ عُمْرَةً وَ لَا يَنْبَغِي التَّخَلُّفُ عَنْهُ أَكْثَرَ مِنْ أَرْبَعِ سِنِينَ
16. ‘Amraki (ibn ‘Ali) narrated through his Isnād from Muḥammad ibn Faďl, from Abī Nāb, who said: I asked Abā ‘Abdillāh (Imam Sādiq ) about (the reward for) going to the Ziyārah of the grave of Ḥusain . Imam said, “Yes. It is equal to performing an ‘Umrah and one should not refrain from (going to) him for longer than four years.”
