5. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from al-Hassan ibn Ali from Al-Thaqafi‘laba ibn Maymun from Zurara ibn ‘A‘yan who has said the following. “I asked Imam abu Ja‘far عليه السلام a question and he answered me. Then an other man came and asked the same question but the Imam gave a different answer. Then a third man came and asked the same question but the Imam gave him an answer that was different from both of the previous answers. When the other two men left I asked the Imam عليه السلام , “Two of your followers from Iraq asked you the same question, how is it that you gave each one a different answer? The Imam replied, “O Zurarah, it is better for us and it gives all of us more time. If you all would say the same thing, people will know that you speak the truth from us and this will leave all of us with less time. Zurarah has said, “I then asked Imam abu ‘Abdallah, ‘Your follows would walk on spears and fire if you would ask them but they come out of your presence with different answers for the same question and the same answer as his father had given.”
