7. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Musa ibn Sa‘dan from ‘Abd Allah ibn al-Qasim from ‘Umar ibn Aban al-Kalbiy from Aban ibn Taghlib who has said the following: “Abu ‘Abd Allah, Alayhi al-Salam, has said, ‘Four thousand angels assigned for the grave of al- Husayn, Alayhi al-Salam, are untidy and dusty. They weep for him until the Day of Judgment. Their chief is an angel called Mansur. They welcome everyone who visits him and escort everyone who says farewell to him. They visit everyone of such visitors if he becomes ill, perform funeral salat (prayer) for those of them who die, and ask forgiveness for him after his death.’”
