H 282 - Saad bin Abdullah Ashari has narrated from Muhammad bin Husain bin Abil Khattab from Hasan bin Ali bin from Thalaba bin Maimoon from Malik Jahni from Asbagh bin Nubatah that he said: I came to Amirul Momineen Ali Ibn Abi Talib عليه السلام and found him thoughtful. He was drawing lines on the ground. I said: “O Chief of believers, why do I see you thoughtful and making lines on the earth? Is it out of desire for the earth?” He said: “No, by Allah, I have never desired it, nor for what is in the world even for a day. I was thinking about the son, who will be born from my seed – my eleventh descendant. He is the Mahdi and he will fill the earth with equity as it will be full of oppression and injustice. There will be perplexity and occultation regarding him, in which communities will go astray and communities will be guided.”
