Худ 11:54

The Prophet Hud’s community raised the point that he had no proof or argument in favour of his being right. This does not really mean that Hud had no argument to prove the truth of his message. He certainly had such arguments, but it did not appear to be so to his opponents. The reason for this was that man is generally unable to test statements purely on the basis of reason or rationality, but sees them from a point of view opposite to that of the presenter of the statements. Since the presenter at that time did not appear to the people to be a man of considerable status, his word did not carry any weight with them. When anyone sets out to invite others to pure unadulterated religion, leaving aside the well-established religion of the day, it invariably happens that in the prevailing atmosphere he becomes a stranger and is reduced to insignificance. People even look upon him as if he were suffering from some mental illness. This was what happened in the case of the Prophet Hud. That is why his people were emboldened to say, ‘We think that some curse has been cast on you by our holy men.’ But after the completion of theoretical arguments, the proof of the veracity of the preacher of Truth is always such that his opponents are unable to subdue him, in spite of every effort.
