Hawzah News Agency –There is a logical relationship between the performance of miracles and the veracity of the claim to prophethood. For if the one who works miracles is truthful in his claims, the proof of the claim will be confirmed; and on the other hand, were the person lying in his claims, it would not be feasible to presume that God, the All-Wise, who wishes right guidance for His slaves, would place such miraculous powers at his disposal. For people, upon witnessing such powers, would believe in the one possessing them, and would act upon what he said. Thus, whenever such a false prophet would lie, his followers would be led astray and such a state of affairs is incompatible with the justice and wisdom of God. This position flows logically from the principle of discernment between good and evil that has been discussed earlier.
