6-19 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Muhammad ibn Al-Hussein Abil Khattab, on the authority of al-Hakam ibn Meskin al-Thaqafi, on the authority of Salih ibn Oqbah that Ja’far ibn Muhammad (as-Sadiq) صلى الله عليه وعلى آله وسلم said, “When Abu Bakr died and Umar tookover, he returned to the mosque and sat down. A man came to him and said, “O Commander of the Faithful! I am one of the Jews. I am one of their scientists. I have several questions to ask you. If you answer them I will become a Muslim.” Umar said, “What are those questions?” He said, “Three, three and one. If you are ready I will ask them, but if there is someone more knowledgeable than you in your tribe direct me to him.” Then Umar said, “Go to that young man - that is Ali ibn Abi Talib صلى الله عليه وعلى آله وسلم.” The man asked him صلى الله عليه وعلى آله وسلم his questions. Ali صلى الله عليه وعلى آله وسلم said, “Why did you say three, three and one? Why didn’t you say seven?” The Jew said, “Since then I would be ignorant. Should you not answer the first three, I will suffice and not ask the rest.” Ali صلى الله عليه وعلى آله وسلم said, “Will you become a Muslim if I answer the first three questions?” The man said, “Yes.” Then Ali صلى الله عليه وعلى آله وسلم said, “Ask.” He said, “I want to ask you about the first stone placed on the Earth, the first spring gushed forth and the first tree grown.” Ali صلى الله عليه وعلى آله وسلم said, “O Jew! You say that the first stone place on the Earth is the one in the Holy House of Bayt ul-Maqdis. But you lie. It is the stone that Adam brought down to Earth from Heaven.” He said, “You are right! By God, Aaron wrote this down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.” Ali صلى الله عليه وعلى آله وسلم said, “You say that the first spring which gushed forth from the Earth was the one in the Holy House of Bayt ul-Maqdis. But you lie! It is the Spring of Life in which Yush’a ibn Noon washed that fish. It is the same spring from which al-Khizr drank. Whoever drinks from it will live forever.” The Jew said, “You are right! By God, Aaron wrote this down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.” Ali صلى الله عليه وعلى آله وسلم added, “You say that the first tree grown on the Earth was an olive tree. But you lie! That tree was al-Ajwa which Adam brought down with him to the Earth from Heaven.” He said, “You are right! By God, Aaron wrote this down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.” The Jew said, “And now for the second three. How many Divine Leaders does this nation have to guide them who will not lose anything if all the people stop following them?” Ali صلى الله عليه وعلى آله وسلم said, “Twelve Divine Leaders!” The Jew said, “You are right! By God, Aaron wrote this down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.” The Jew asked, “Where does your Prophet reside in Paradise?” Ali صلى الله عليه وعلى آله وسلم said, “In the highmost place and the noblest location in the Eternal Paradise.” The Jew said, “You are right! By God, Aaron wrote this down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.” The Jew asked, “Who are the people who live with him in the same house?” Ali صلى الله عليه وعلى آله وسلم said, “The twelve Divine Leaders.” The Jew said, “You are right! By God, Aaron wrotethis down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.” Then the Jew said, “And now for the seventh question. For how many years will his successor live after him?” Ali صلى الله عليه وعلى آله وسلم said, “For thirty years.” The Jew asked, “What will happen next? Will he die or will he get killed?” Ali صلى الله عليه وعلى آله وسلم said, “He will be killed. He will be struck on the crown of his head with a sword and his beard will be covered with blood.” The Jew said, “You are right! By God, Aaron wrote this down which was dictated to him by Moses صلى الله عليه وعلى آله وسلم.”(The author of this book (Sheikh Sadooq) said,) There are other sources for this tradition which I have presented in the book KAMAL AD-DIN WA TAMAM AN-NE’MAH FI ITHBAT AL-GHAYBA WA KASHF AL-HAYRA.
