 3. Muhammad ibn Yahya and al-Hassan ibn Muhammad have narrated from Ja’far ibn Muhammad from al-Hassan ibn Muhammad al-Sayrafi from Ja’far ibn Muhammad al-Sayqal from his father from Mansur who has said the following. “Abu ‘Abdallah  said to me, “O Mansur, this matter (the rise of al-Mahdi with Divine Authority) will not come to you before despair, and not, by Allah, before (your good ones are) distinguished (from evil ones) and not, by Allah, before you are refined and not, by Allah, before tuning to misfortune of those who act in evil and before reaching salvation of those who seek salvation.”
