﴿ وَٱلَّذِينَ كَفَرُوا۟ وَكَذَّبُوا۟ بِـَٔايَٰتِنَا فَأُو۟لَٰٓئِكَ لَهُمْ عَذَابٌۭ مُّهِينٌۭ ﴾

“whereas for those who were bent on denying the truth and gave the lie to Our messages, there shall be shameful suffering in store.”

A prophet’s call is marked by the greatness of convincing arguments. But those who are accustomed to seeing only outward greatness, are unable to detect the inner greatness of the prophet and consequently deny it. Such people are always in doubt because they want to see the Truth in external glory. And it is the way of God that He brings Truth in the abstract to people, so that those who recognise Truth may acknowledge it and attach themselves to it and those who are enamoured of outward show may ignore it and prove themselves finally guilty. Denying the signs means that man ignores the Truth, even when it is supported by sound argument. He is not willing to accept the Truth, even if it is staring him in the face.
