Ibn Sirin said: Ibn al-Zubayr (may Allah be pleased with them both) said: "Everything Ka'b used to tell us has come to pass, except his saying that a young man of Thaqif would kill me, while here is his head placed before me," meaning al-Mukhtar. Ibn Sirin said: And he did not know that Abu Muhammad, meaning al-Hajjaj, had been kept in store for him.
