9. Muḥammad ibn ‘Abdillāh ibn Ja’far Al-Ḥimyari narrated to me from his father, from Ya’qūb ibn Yazīd, from Muḥammad ibn Abī ‘Umayr, from Zayd Al-Shaḥḥām, who said: Abū ‘Abdillāh (Imam Sādiq ) said: Allāh will forgive all of the past and future sins of those who go to the Ziyārah of the grave of Ḥusain on the fifteenth of Sha’bān.
