12-41 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Muhammad ibn al-Hussein ibn Abil Khat’tab, on the authority of Al-Hikam ibn Meskin al-Saqafy, on the authority of Salih ibn Aqabah, on the authority of Ja’far ibn Muhammad as-Sadiq (MGB), When Abu Bakr died and Umar took over the Caliphate, Umar went to the mosque and sat down. A man entered the mosque and said, ‘O commander of the faithful (referring to Umar)! I am one of the Jews. I am their great scholar. I wish to ask you about some problems. I will embrace Islam if you can convince me.’ Umar said, ‘What are they?’ He said, ‘Three, three and one. I will ask you if you please or guide me to ask anyone else who is more knowledgeable if you wish.’ Umar said, ‘Go and ask that young fellow who is Ali ibn Abi Talib (MGB).’ The Jew went to Ali (MGB) and asked him questions. Ali (MGB) said, ‘Why did you say three, three and one but did not say seven?’ The Jew said, ‘That would have been due to my ignorance! If you could not answer the first three questions, there would be no need to ask the rest.’ Ali (MGB) said, ‘Will you accept Islam if I give you the correct answers?’ The Jew said, ‘Yes, I will.’ Then Ali (MGB) said, ‘Go ahead and ask.’ The Jew asked, ‘Which were the first rock placed on the Earth, the first spring which gushed out of the Earth and the first tree which grew on the Earth?’ Ali (MGB) replied, ‘O Jew! You say that the first rock placed on the Earth was the one in Bayt ul- Muqadas (Holy Shrine in Jerusalem), but you lie. It was the rock which Adam brought down to the Earth from Heaven. You say that the first spring which gushed out of the Earth was one in Bayt ul-Muqadas (Holy Shrine in Jerusalem) but you lie. That spring was the spring of youth in which Yushu ibn Noon washed the fish and the same one from which Khizr drank. Whoever drinks from it will become eternal.’ The Jew said, ‘You are right. This has been recorded in Aaron’s handwriting on the authority of Moses.’ Then Ali (MGB) continued, ‘You say that the first tree which grew on the Earth was an olive tree but you lie. It was the Al-Ajwatdate which Adam brought down to the Earth from Heaven.’ The Jew said, ‘You are right. This has been recorded in Aaron’s handwriting on the authority of Moses.’ Then the Jew asked, ‘Where in Paradise does your Prophet sit?’ Ali (MGB) said, ‘In the noblest and highest place in the Adan Gardens.’ The Jew said, ‘You are right. This has been recorded in Aaron’s handwriting on the authority of Moses.’ Then the Jew asked, ‘Who will accompany him in his place of residence?’ Ali (MGB) replied, ‘The twelve Divine Leaders.’ The Jew said, ‘You are right. This has been recorded in Aaron’s handwriting on the authority of Moses.’ Then the Jew asked the seventh question and accepted Islam. He asked, ‘For how many years will his Trustee live after him?’ Ali (MGB) said, ‘Thirty years.’ He asked, ‘Will he die or will he get killed?’ Ali (MGB) replied, ‘He will be killed with such a blow on the head that his beard will become red with his blood.’ The Jew said, ‘You are right. This has been recorded in Aaron’s handwriting on the authority of Moses.’”I have recorded this book from its various chains of narrators in Awael.
