The Statements and the Explicit Texts on Leadership with Divine Authority) of the Twelve Imams  عليه السلام — report 19

19. Ali ibn Muhammad and Muhammad ibn al-Hassan have narrated from Sahl ibn Ziyad from mmd ibn al-Hassan ibn Shammun from ‘Abdallah ibn ‘Abd al-Rahman al-Asamm from Karram who has said the following. “I took an oath with my self that I will not any food during the day until the rise of Al-Qa’im (the rise of al-Mahdi with Divine Authority). I then went to see abu ‘Abdallah عليه السلام .” The narrator has said, “A man from you Shi‘a (followers) has imposed on himself on oath not to eat any food during the day until the rise of Al-Qa’im from the family of Muhammad صلى الله عليه وعلى آله وسلم (the rise of al-Mahdi with Divine Authority).” The Imam عليه السلام said, “Fast, then O Karram. Do not fast on the two ‘Id days and the three days of Tashriq (11,12,13) of the month of Dhil Hajj. Also do not fast when you are on a journey or when you will have an illness. It is because when al-Husayn was murdered the heavens and the earth and all the angles in them mourned and lamented before the Lord. They said, “Lord, grant us permission to destroy the creature and purge the earth from them because of their disregard of you reverence and their murdering your chosen people. Allah then inspired them, “My angels, My heavens and My earth be patient and relieved.. He then removed a barrier of the barriers and there appeared Muhammad and the twelve executors of his will. He then held the hand of so and so, Al-Qa’im (the one who will rise with Divine Authority) from among them and said, ‘O My angels, My heavens and My earth through this I will grant support for this.” He said it three times.”
