An Ahmadi, when challenged to prove the coming of Imam Mahdi from Quran responds:
"......Mubashir Inayet yes You may read Surah Al jumma .It speaks of two comings. The holy prophet of Islam pbuh would appear in Ummiyeen as well as in Akhareen.Tow descents are mentioned in The Holy Quran.
Ist advent would occur in the unlettered people in UMMIYEEN ( which happened 1500 years ago) and the second advent occur in the people of latter days in AKHAREEN the latter people who have not yet met with Sahabahs.
Bukhari illustration reveals that this verse disloses the coming of a male who would be from Persian origin from Salman Farsi people.
He is the one would succeed to bring back faith from heaven and establish it in land. This is a clear sign of Mahdi recorded by the Holy Quran...."
Here is what Sura Jumma 62:2-3 says:
62:2 He is the One Who has sent a Messenger among the unlettered ones to convey to them His messages, to make them grow in humanity, to teach them the Law and the wisdom behind it. Whereas before that they were obviously lost in error,
62:3 Along with others who have not yet joined them (in time and place). He is Mighty, Wise.
Clutching at straws?
