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 عليه السلام) said: The minimum reward for those who go to the Ziyārah of Ḥusain عليه السلام 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.
