91. In this verse, the addressees are the entire mankind. It means: O mankind, in reality all of you belonged to one community and had one and the same religion and all the Prophets brought one and the same creed which was this: Allah alone is the Lord of all mankind, therefore they should worship Him alone. But afterwards the people corrupted this creed and invented and adopted the things they liked and mixed their own theories, whims and practices in it. This brought into being countless communities and religions. Thus it is absolutely wrong to say that a particular Prophet was the founder of a particular religion and another of another, and so on. The very fact that different religions came into being at different periods of time, does not prove that the Prophets created these differences. It is obvious that the Prophets of God could not found different religions nor could they teach their followers to worship any beings other than Allah.
