Some Ans. Questions 2014 by -'Abdu'l-Bahá- 1 Para

It often happened in Baghdad that Muslim, Jewish, and Christian divines and European men of learning would be gathered in His blessed presence. They would each ask a different question and, despite their varying beliefs, would each receive so complete and convincing a reply as to be fully satisfied. Even the Persian divines residing in Karbila and Najaf[12] chose a learned man by the name of Mulla Hasan 'Amú and dispatched him as their representative. He came into His blessed presence and asked a number of questions on their behalf, to which Baha'u'llah responded. He then said, "The divines fully recognize the extent of your knowledge and attainments, and it is acknowledged by all that you are without peer or equal in every field of learning. It is moreover evident that you have never studied or acquired this learning. But the divines say that they are not satisfied with this and cannot acknowledge the truth of your claim on the basis of your knowledge and attainments alone. They therefore ask you to produce a miracle in order to satisfy and assure their hearts." (9:6) com1
