8. Muhammad ibn Yahya has narrated from Muhammad ibn ’Abd al-Jabbar from ibn Faddal from Hammad ibn ‘Uthman from ’Abd al-‘Ala’ ibn A‘yan who has said the following. “Abu ‘Abdallah عليه السلام would say, ‘I was born of the descendents of the holy Prophet صلى الله عليه وعلى آله وسلم while I knew the book of Allah wherein is the knowledge of how the world was first created and the knowledge of all that may come up to the Day of Judgement. Therein is the news of the heavens and the earth, the news of the Paradise and the Fire hell, the news of things of the past, those that will come into existence. I know all of these just as I can see in the palm of my hands. Allah says, “In it there is an explanation of everything.’”
