(44) Muhammad bin Hammam narrated from Ja’far bin Muhammad bin Malik from Umar bin Tarkhan from Muhammad bin Issma’eel from Ali bin Umar bin Ali bin al-Husayn that Abu Abdullah Ja’far bin Muhammad as-Sadiq had said: “Al-Qa’im is one of my descendants. His old is like Abraham’s old; one hundred and twenty years. He is recognized and then he disappears for a period of time and then he reappears as a young man of thirty-two years old. Some groups of people deviate from him. He fills the world with justice after it has been filled with injustice and oppression.”
