Al-Kharaij: It is narrated from Abul Qasim Ja’far bin Muhammad binQuluwayh that he said:
“In the year 337 A.H. I had the honor of performing the Hajj and enrouteto it reached Baghdad. That year after the destruction of Qaramtians, they had returned Hajar al-Aswad to its prior place. Most of my efforts were aimed to find someone who would fix that stone in its original spot. Because I had learnt from books that except for the Divine Proof of the time, no one can fix it in its original spot. As was seen during the time of Hajjaj when Imam Zainul Abideen (a.s.) placed it in its original spot. But I fell severely ill and began to fear for myself, and in that condition I was not able to continue my journey. Then I learnt that Ibne Hisham was traveling to Mecca. Therefore, I wrote a letter, sealed it and entrusted it to him. In that letter I had asked about the span of my life, that whether I was destined to die during this illness or not. And I told Ibne Hisham: My endeavor is that this letter should reach the hands of one who fixes the Hajar al-Aswad. And for this job I have summoned you.
Ibne Hisham says: When I reached Mecca and came to the place whereHajar al-Aswad was supposed to be fixed, I gave an amount of cash to thecaretakers of the Haram to allow me to remain there at that fixed time. I tookup a location from where I could see who fixes that stone. I told the guards toremain with me so that they may take me away from the crowd. I saw thateveryone was trying to fix the stone but none was able to do so and it used tofall down. Then a young man of wheat complexion and an elegant appearance approached; he took the stone and placed it in the proper spot. It became so
well fixed that I imagined it must not have been so even in the beginning.Clamor arose from the people due to that and that young man headed towardsthe exit. I rose from where I was sitting and went after him. I pushed peopleto right and left and they thought I had gone insane. People were making wayfor him and I did not let him get out of my sight till he separated from thepeople. I was walking very fast and he moved calmly and with composure.When he reached a place where none could see him except me, he turned tome and said: Give me that which you are carrying. I presented the letter tohim. Without looking at it he said: Tell him that there is no danger for him inthis illness and the death from which he is helpless would come after thirtyyears. Tears filled up my eyes and I could not even move. He left me in thiscondition and went away.
Abul Qasim says: This incident was related to me by Ibne Hisham.
The narrator adds: Thirty years after that mysterious incident Abul Qasimfell ill. So he gathered his affairs, wrote down his will and he madeexceptional efforts in this regard. They asked him: “What fear is that? Weexpect that the Almighty Allah would again give you good health.” Hereplied: “This is the year about which I was warned.” He passed away in thatillness. May Allah have mercy on him.
