1. Ahmad ibn Idris al-Qummi and Muhammad ibn Yahya have narrated from al-Hassan ibn Ali al-Kufi from Musa ibn Sa‘dan from ‘Abdallah ibn Ayyub from abu Yahya al-San‘ani from abu ‘Abdallah who has said the following. “O abu Yahya, on every Friday night there is a special task for us to pursue.” The narrator has said that he asked the Imams , “May Allah take my soul in service for your cause, of what nature is this special task?” The Imam said, “The spirits of the deceased prophets and the spirits of the deceased executors of the will of the prophets and the spirit of the executor of the will of the Holy Prophet living with you now are all taken to heavens until they arrive to the throne of their Lord and then walk around it seven times. They perform prayers near every column of the columns of the throne, in a two Rak‘at form after which they are returned to their bodies in which they were before. The prophets and the executors of the will of the prophets become full of joy and the executor of the will of the Holy Prophet living with you receives a huge increase in his knowledge.”
