Promised Messiah (As)

I saw [in a vision] that I was standing on a pulpit in the city of London and was setting forth the truth of Islam in the English language, in a very well reasoned address. Thereafter, I caught several birds who were sitting upon small trees and were of white color and their bodies resembled the bodies of partridges. I interpreted this vision as meaning that though I would not be able to travel to that country, my writings will be published among them and many righteous English people will be attracted by the truth.
