47-43 Muhammad ibn Musa ibn al-Mutawakkil - may God be pleased with him - narrated that Abdullah ibn Ja’far al-Hemyari quoted on the authority of Ahmad ibn Muhammad ibn Isa, on the authority of Sa’eed ibn Sa’d,

“Abul Hassan Ar-Ridha’ looked at a man and said, ‘O Servant of God! Make a will regarding what you wish to be done after your death and prepare yourself for that from which there is no escape.’ Exactly what the Imam had said happened three days later (i.e. the man died).”
