﴿ قَالَ لَقَدْ عَلِمْتَ مَآ أَنزَلَ هَٰٓؤُلَآءِ إِلَّا رَبُّ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ بَصَآئِرَ وَإِنِّى لَأَظُنُّكَ يَٰفِرْعَوْنُ مَثْبُورًۭا ﴾

“Answered [Moses]: "Thou knowest well that none but the Sustainer of the heavens and the earth has bestowed these [miraculous signs] from on high, as a means of insight [for thee]; and, verily, O Pharaoh, [since thou hast chosen to reject them;] I think that thou art utterly lost!"”

When clear signs were shown to the Pharaoh, he said that this was magic. This shows how powerful an argument and how great the signs of God that are presented by the preacher to the addressee, it is still open to man to reject the message by uttering some words which he thinks to be logical. He may call divine signs a form of magic produced by man, or ignore its rational proofs as carrying no academic weight and as such unacceptable. When the opponents fail in suppressing the call of truth by verbal opposition, they stoop to aggressive activities against the messenger of truth, forgetting that this was not a human, but a divine matter. Who can succeed in the matter of God by resorting to aggression?
