5 حَدَّثَنِي أَبُو الْعَبَّاسِ الرَّزَّازُ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ الْحُسَيْنِ بْنِ أَبِي الْخَطَّابِ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنِ الْخَيْبَرِيِّ عَنِ الْحُسَيْنِ بْنِ مُحَمَّدٍ الْقُمِّيِّ قَالَ قَالَ أَبُو الْحَسَنِ مُوسَى (ع) أَدْنَى مَا يُثَابُ بِهِ زَائِرُ الْحُسَيْنِ (ع) بِشَاطِئِ الْفُرَاتِ إِذَا عَرَفَ حَقَّهُ وَ حُرْمَتَهُ وَ وَلَايَتَهُ أَنْ يُغْفَرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ وَ مَا تَأَخَّرَ
5. Abul ‘Abbās Al-Razzāz narrated to me from Muḥammad ibn Ḥusain ibn Abil Khaťťāb, from Muḥammad ibn Ismā’īl, from Al-Khaybari, from Ḥusain ibn Muḥammad Al-Qummi, who said: Abul Ḥasan, Mūsā (Imam Kāżim ) said: The minimum reward for those who go to the Ziyārah of Ḥusain by the shores of the Euphrates (River) while knowing his rights and believing in his sanctity and Wilāyah is that all of their past and future sins will be forgiven.
