Imam al-Hadi (a.s.) said, “Once, a Jew came to Amir’ul- Mu’minin Imam Ali (a.s.) and said to him, ‘Tell me about that which is not of Allah(God), that which Allah does not have, and that which Allah does not know!’
Imam ‘Ali (a.s.) said, ‘What Allah does not know is that He does not know (accept) that He has a child. This refutes your (the Jews’) saying that Uzayr is the son of Allah. As for that which is not of Allah, it is injustice because there is no injustice with Allah against His people. And as for your saying about that which Allah does not have, it is that Allah has no partner.’
The Jew was astonished and became Muslim. He declared the shahada and then said to Imam ‘Ali (a.s.), ‘I bear witness that you are the truth, from the people of truth, and have said the truth.’
Imam ‘Ali (s.a) was the gate of the City of the Prophet’s knowledge. If he was given his right (in the caliphate), he would have given verdicts to the people of the Bible from their Bible, to the people of the Psalms (Zabur) from their Psalms, and to the people of the Torah from their Torah. He often said that if the caliphate (vicegerency) had come to him after the death(Martyr) of the Prophet (S), every Jew or Christian would have turned Muslim and followed the path of the truth.
