 2. Ali ibn Muhammad has narrated from Muhammad ibn ’Isma‘il ibn Ibrahim ibn Musa ibn Ja‘far  who has said the following. “Once abu Muhammad  wrote to abu al-Qasim Ishaq ibn Ja‘far al-Zubayri before the death of al-Mu‘tazz by about twenty days as herein below. ‘Stay home until what is to happen will happen.’ When Burayha was killed he wrote to him, “A happening has happened. What would you command me to do?” He wrote back, “This is not the happening. It is another happening.” Then there was the case of al-Mu‘tazz the way it was.” It is narrated from the same narrator that the Imam  wrote to another person. “Muhammad ibn Dawud ibn ‘Abdallah will be killed.” It was ten days before his murder. On the tenth day he was killed.”
