The third query is who was the man who traveled the whole of the east and the west and reached the point of sunrise and sunset until he went up to the wall of Yajooj and Majooj and what is his story? Then they narrated the replies known to them and said that if he (Prophet) Muhammad says what we have said then he is a true Messenger. If his reply is other than this do not testify to his Prophethood. Then they asked what the fourth question was?

They said, ask him when the Resurrection Day will arrive. If the says that he knows when it will occur then he is a liar, because, the knowledge of the Last Day is with none but Allah.” So they left the Jewish clergy and came back to Abu-Talib and told him that his nephew claimed that he was getting news from the heaven. “So we want to test him by some questions. If he gives the correct replies then he is true.

Otherwise we will know that his claim is false.” Abu-Talib said, “Ask him whatever you want.”
