10. Muḥammad ibn Ḥasan ibn ‘Ali ibn Mahziyār narrated to me from his father, from his grandfather ‘Ali ibn Mahziyār, from Ḥasan ibn Sa’īd, from ‘Ali ibn Ḥakam, from ‘Arafah, from Rib’ī, who said: Abū ‘Abdillāh (Imam Sādiq عليه السلام) said: “The shores in the right side of the valley” (28:30), which Allāh has mentioned in His Book, is the Euphrates (River); “the blessed spot” (28:30) is Karbalā and “the tree” (28:30) is Muḥammad صلى الله عليه وعلى آله وسلم.
