A Prophet who loudly claims prophethood for himself is, in reality, issuing the human beings with a challenge to enter the field of struggle against him with greater seriousness and energy than his, through mobilizing all their capacities and resources. But despite their desperate efforts, they get nowhere in their confrontation with him, and in their utter impotence they are obliged to surrender.
The miracle of the Prophet is by its very nature a demonstration of his connection with the source of all being and the world of revelation; its properties are such that it is impossible for the human beings who are not connected to the world beyond nature to confront or resist it, however much they expend of their powers and energies.
Hence the demonstration of prophethood depends on the performance of a deed that transcends the limits set by natural norms and common laws, and the performance of such a deed is not possible without the permission of the Creator. This provides a criterion for distinguishing the true from the false.
Naturally, the miracle differs from other phenomena in the world only from our point of view, not from the point of view of the One Who has precise and complete knowledge of all the causes of existence. Generally speaking, the proof of prophethood was provided by miracles in areas that were in each age the object of special attention, so that those specialized in each area might know that the deed in question was beyond the limits of human capacity.
This is the starting point for the task of the Prophets; by taking into account the human beings' level of intellectual development, they conquer broad horizons of human belief and swiftly attain their exalted goals. Denial and Negation on the Basis of Pride Those who regard miracles as something impossible and unacceptable should know that their incredulity arises from a superficial and simplistic view of things.
Many events occur in the material world of which the human being knows the causes, but there are other events which the natural sciences are unable to interpret and explain. We should not, therefore, arrogantly deny everything the cause of which is unknown to us, relying on our slight knowledge. The human being's error is to imagine that he knows everything; when he cannot penetrate the depths of a problem, he proceeds simply to deny it.
