47-7 Muhammad ibn Ali Majilawayh - may God be pleased with him - narrated that his uncle Muhammad ibn Abil Qasim quoted on the authority of Muhammad ibn Ali al-Kufi, on the authority of Al-Hassan ibn Ali al-Hadhdha’, on the authority of Yahya ibn Muhammad ibn Ja’far, “My father fell really ill. Abul Hassan Ar-Ridha’ came to visit him. My uncle Ishaq was sitting there crying hard for him.” Yahya added, “Abul Hassan turned to me and said, ‘Why is your uncle crying?’ I said, “From the fear of what you see.” Abul Hassan looked at me and said, “Do not worry. Ishaq will die before him.” Yahya added, “My father Muhammad got well and Ishaq died.”The author of this book (a.s.heikh Sadooq) - may God have Mercy upon him - said, “Ar-Ridha’ knew this based on what he possessed called the Book of Calamities in which it is recorded how long each member of this family would live. They have inherited this book from God’s Prophet (S). When Ali - the Commander of the Faithful said the following, he was referring to this very same book, “I have been granted the knowledge of afflictions, calamities and relationships, plus the resolution of conflicts.”
