Why were the people of ancient Makkah so inclined that, wherever they saw God’s punitive devices falling from the sky, they would say that it was only a cloud? The reason for this was not that they did not accept God or His powers. The real reason for this was that they were doubtful of the Prophet really being a prophet. They were not convinced that the rejection of the person who was before them and who was apparently just like them could be so great a crime as to bring down a mountain of destruction upon them. The personality of the Prophet Muhammad was a matter of controversy among his contemporaries. He had at that time no established reputation, as it would seem to people today. But, it is the real test of man that he should see the reality by tearing asunder the veils of doubt. He should be able to discover the essence of the established personality in the apparently controversial personality.
