4. Muḥammad ibn ‘Abdillāh ibn Ja’far Al-Ḥimyari narrated to me from his father, from ‘Ali ibn Muḥammad ibn Sālim, from Muḥammad ibn Khālid, from ‘Abdillāh ibn Ḥammād Al-Basri, from ‘Abdillāh ibn ‘Abdil Raḥmān Al-Asam, from Hishām ibn Sālim, who said: A man came to Abī ‘Abdillāh (Imam Sādiq ) and asked – as part of a longer Ḥadīth, “Should one go to the Ziyārah of your father (Ḥusain )?” Imam replied, “Yes.” The man asked, “What is the reward for those who perform Ghusl with the water of the Euphrates (River) and then go to him (Ḥusain )?” Imam replied, “If they perform Ghusl with the water of the Euphrates (River) with the intention of going to him, their sins will fall off of them (and they will become sinless) like the day their mothers gave birth to them.”
