6. Muḥammad ibn ‘Abdillāh ibn Ja’far 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, “O son of the Messenger of Allāh! Should one go to the Ziyārah of your father (Ḥusain )?” Imam replied, “Yes and establish prayers next to his grave. But one should not establish prayers in front of the grave, but rather, should stand behind it when establishing prayers.”
