My father and all of my scholars narrated to me from Sa’d ibn ‘Abdillāh, from Muḥammad ibn ‘Isā ibn ‘Ubayd Al-Yaqťīni, from Muḥammad ibn Ismā’īl Al-Basri, from someone who narrated to him, who said: Abū ‘Abdillāh (Imam Sādiq عليه السلام) said: The sacred boundaries of the grave of Ḥusain عليه السلام are one parasang by one parasang from each of its four sides.
