6. My father and Muḥammad ibn Ḥasan narrated to me from Ḥusain ibn Ḥasan ibn Abān, from Ḥusain ibn Sa’īd, from Ibn Abī ‘Umayr, from Ḥammād ibn ‘Uthmān, from Al-Ḥalabi, who said: I asked Abā ‘Abdillāh (Imam Sādiq ) about the Ziyārah of the grave of Ḥusain . Imam said, “(Go) once a year because I do not want you to be identified.”
