“Once I went to see Amir al-Mu’minin (a.s.) and found him thinking and he drawing lines on the ground. I then said, “O Amir al-Mu’minin (a.s.) I can see you thinking and drawing lines on the ground. Have you become interested in it (worldly things) ?” He said, no, by Allah, I have not become interested in it and the whole world not even for a day but I thought about a baby from my descendants, the eleventh generation. He will be al-Mahdi who will fill the earth with justice and fairness after its being filled with suffering and injustice. He will disappear from the public sight and in confusing conditions. Certain people will deviate and others find the path of guidance.” I then asked, “O Amir al-Mu’minin (a.s.), how long will be the duration of confusion and the disappearance?” He said, “Six days or six months or six years.” I then said, “Will this really come to pass?” He said, “Yes, just his creation will be necessary (so also will be his disappearance). However, O Asbagh, this is not your concern. Those people will of the best in this nation with the best virtuous ones of this family (Ahl al-Bayt).” I then said, “What then will happen afterwards?” He said, “Allah will do whatever He will so decide. He possesses, Bada’s, (seemingly change of plan) wills, goals and ends.”
