Based on this, the strongest reason that can be given is that if the Imam appears and his person is not recognized and identified, it is necessary that he works a miracle to indicate his truthfulness; and it requires reflection to know whether something is a miracle, which can be subject to doubts. Therefore, it is not possible that it be evident from the condition of a person to whom the Imam has not appeared that if he appears to him and shows him a miracle, he may not reflect well and have doubts and believe that he is a liar and spread this information and cause the harm mentioned earlier.
