Apparently this qiyas (analogy) is out of scope here, and the Prophet had no knowledge of the unseen, as he — like common people — used to hold speech of people to be true, when no suspicion being raised against it. Most often he believed the traditions related by even the hypocrites and disbelievers, the fact indicated by the hadith of Arinayn 343 and people of Ma'unah well.

In fact he could recognize the falsity of some liars through wahy (revelation), or some ways of test, or reporting by trustworthy people, and the like ways of human knowledge. It is known that the prophets could be distinguished from ordinary people through revelation and ismah (infallibility) against telling lies.

And revelation was not to be sent down but with matters related to religion, and da`wah (invitation) to it, with safeguarding it and the man who brought it, beside the fact that to believe the liar is not the same as telling lie.

It is sufficient to meditate in this section (bab) admonition from Allah to His Messenger, due to his granting permission to some of the hypocrites who asked him to exempt them from taking part in the Battle of Tabuk, and the justification he gave for this, through saying to him: God forgive thee (O Our Apostle!) Why didst thou give them leave (to stay behind) until it was manifest unto thee who spake the truth, and thou hadst known the liars.

(9:43) When the prophets and messengers are allowed to believe the liar in some matters that neither breach the Din, nor entail a legal rule, or anything inconsistent with the position of message, isn't it permissible for others to believe the liar in every report that no evidence is there to prove its containing any falsity? Whoever believes anything can relate it to any other person without ascribing it to that from whom he heard.

344 About descension of Jesus from the heaven and reappearance of al-Dajjal and al-Mahdi 345 he said: Many traditions about descension of Jesus are reported in the two Sahihs and Sunan and other books, most of which are cited about the last hour (end of time) and mixed with the traditions of al-Dajjal, in which and in the traditions on al-Mahdi (A), there is much confusion, difference and contradiction.

Out of them altogether, it is apparent that among the Jews a dajjal (impostor), and rather the biggest impostor ever known throughout the history of nations, will appear and claim to be Jesus that is awaited by the Jews. At that time a large number of people will be tempted by him.
