I was in the company of Imam Ja’far Sadiq (a.s) when Abul Hasan, Musa (a.s) came with Muhammad [his brother] and a little lamb and each of them were pulling at the lamb till Muhammad managed to pull it away and Abul Hasan was shamed and he came and sat down next to me. I took him in my arms and kissed him. After that Imam Ja’far Sadiq (a.s) said: He is your master and Imam; in spite of this, Bani Abbas would arrest him and he would bear hardships from them, but Almighty Allah would release him from their clutches in any way He likes. After that he would go into occultation, till people would start mourning for him and would be extremely terrified. Then Allah, the Mighty and the High will bestow deliverance of the world and hereafter through his hands.
