Commentators have narrated; a group of the chief and officials of Mecca went to Medina, and paid a visit to the Jewish elders, rabbis, and learned men. They asked the Jews questions about Mohammad and his claim of being the Messenger of God or prophet. They asked to know, if at all there could be something as a prophet or the Messenger of God. and if yes; What signs and symptom, the claimant should have?

      In answer to the Meccan, the Jews said:ِ

      ``You should ask Mohammad of three questions. If he did answer you correctly, know him to be the truthful Messenger of God, as he claims; but if he failed to answer, you must consider him as liar.'' The questions were as follows:ِ

1ِ Who were the youth of the ancient who departed from their people?

2ِ Who was the Man who went all round the world and who reached the East and the West of the earth?

3ِWhat is the truth about Man's spirit?

      The Meccan returned home and asked the prophet to answer them the above questions. The prophet said to the questioners that, he would give them the answer next day, while he had forgotten to add, ``IF GOD SPEED'' For this mistake he was not inspired for a couple of weeks; and this made the prophet very anxious! He waited for some 15 days, when at last he was forgiven and GABRIEL appeared again, and brought down the answers. The one concerning the spirit was inserted among the verses of the chapter of ASRÄِS 17:84. The next two questions were answered in the chapter of CAVE=18
