“O Amirul Mo’mineen, I want to ask you three questions.” Amirul Mo’mineen said: “Ask whatever you like.” The man said: “Would you tell me if man sleeps where his soul goes to? How does man remember and forget? How do man’s children look like their uncles; their father’s brothers and mother’s brothers?” Amirul Mo’mineen (as) turned to his son al-Hasan (as) and said to him: “O Abu Muhammad, answer him!” Imam al-Hasan (as) said to the man: “As for your question that when man sleeps whereto his soul goes, his soul is hanging in the air until he moves during his wake, so when Allah permits that that soul is to go back to the body, the soul attracts the air to settle in its body but if Allah does not permit that soul to get back to that body, the air will attract the soul away from the body until the Day of Resurrection. But as for what you asked about remembering and forgetting, the heart of man has been created to comply with the truth and there is a cover on the truth. If he prays Allah to have blessing upon Muhammad and his family in a perfect way, that cover will be removed from upon the truth and the heart will shine then one will remember what he has forgotten but if he does not pray Allah to have blessing upon Muhammad and his family or his prayer is imperfect, the cover will get closed on the truth and the heart will be dark and then he will forget what he has remembered. As about a newborn baby that looks like the uncles, if a man goes to bed with his wife with calm heart, tranquil nerves and undisturbed body, his sperm will settle inside the womb and the baby will looks like either its father or its mother. If a man goes to bed with his wife with upset heart, unquiet nerves and disturbed body, the sperm also will upset and fall on some veins. If it falls on a vein of the father’s brothers, the baby will look like the father’s brothers and if it falls on a vein of the mother’s brothers, the baby will look like the mother’s brothers.” The man said: “I witness that there is no god but Allah and I will keep on that. I witness that Muhammad is the messenger of Allah and I will keep on that. (He pointed to Imam Ali (as) with his hand and said) I witness that you are the guardian of the messenger of Allah and the successor of his authority and I will keep on it. (He pointed to Imam al-Hasan (as) and said) I witness that you are his guardian and the successor of his authority and I will keep on it. I witness that al-Husayn bin Ali is his (al-Hasan’s) guardian and the successor of his authority and I will keep on that. I witness that Ali bin al-Husayn is the guardian of al-Husayn. I witness that Muhammad bin Ali is the guardian of Ali bin al-Husayn. I witness that Ja’far is the guardian of Muhammad (bin Ali). I witness that Musa is the guardian of Ja’far. I witness that Ali (bin Musa) is the guardian of Musa. I witness that Muhammad (bin Ali bin Musa) is the guardian of Ali (bin Musa). I witness that Ali (bin Muhammad) is the guardian of Muhammad. I witness that al-Hasan is the guardian of Ali and I witness that a man from among the offspring of al-Husayn, who is not named or surnamed until he appears by the will of Allah to spread justice allover the earth after it has been filled with injustice and oppression, is the guardian of al-Hasan bin Ali. Peace, mercy and blessing of Allah be upon you, O Amirul Mo’mineen.” Then he left. Then Amirul Mo’mineen said to Imam al-Hasan: “O Abu Muhammad, follow after him and see where he goes to!” Imam al-Hasan said: “I followed after him, but since he put his leg out of the gate of the mosque I could not know where he disappeared. I came back and told Amirul Mo’mineen (as). He said to me: “O Abu Muhammad, do you know who he is?” I said: “No, Allah, His messenger and Amirul Mo’mineen are more aware.” He said: “He is al-Khidr (as).”
