16. And it was narrated to me by Muhammad b. al-Hassan who said it was narrated to us by Muhammad b. al-Hassan al-Saffar from Ahmad b. Muhammad from Ali b. al-Hakam who said it was narrated to us by Ali b. Hamzah from Abi Basir from Abi Abdillah who said: “The Almighty Allah has appointed seventy thousand angels, distressed and having their hair covered in mud to send salutations on the grave of Imam Husain everyday. They pray for the person who comes for Ziyarat of Imam Husain saying, “O Lord! These are the visitors of Imam Husain do this and that for them.”
