Nature of Prophecies
Hazrat Mirza Ghulam Ahmad of Qadian (as)
The truth is that so far as prophecies are concerned it has always been the practice of God that He keeps a sort of secrecy and an aspect of trials in them. Had that not been the case, there would have never arisen any differences and all the people would have belonged to one and the same religion. In order to create some distinction, God has willed there to be some sort of hidden aspect in the prophecies, and a trial. Those who can look at the things only superficially stick to the words and are led far away from the reality. That was the difficulty that the Jews were confronted with; they started doubting the position of the Holy Prophet (sallallaho alaihi wa sallam). If the Biblical prophecy had been clearly indicative of the fact that this prophet would be descendant of Hazrat Ishmael and his name would be Muhammad (sallallaho alaihi wa sallam), his father’s name would be Abdullah son of Abdul Muttalib and his mother would be Aamina, the Jews would have never rejected him. But unfortunately for them, this detail was not mentioned in the prophecy; the prophecy mentioned his as being from among ‘your brethren’; they took it to mean that he would be from among the children of Israel.
