﴿ فَإِنْ حَآجُّوكَ فَقُلْ أَسْلَمْتُ وَجْهِىَ لِلَّهِ وَمَنِ ٱتَّبَعَنِ ۗ وَقُل لِّلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ وَٱلْأُمِّيِّۦنَ ءَأَسْلَمْتُمْ ۚ فَإِنْ أَسْلَمُوا۟ فَقَدِ ٱهْتَدَوا۟ ۖ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا عَلَيْكَ ٱلْبَلَٰغُ ۗ وَٱللَّهُ بَصِيرٌۢ بِٱلْعِبَادِ ﴾

“Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures.”

The call of the Quran is the call of the same true version of Islam, the religion of submission to God, as was revealed to all the other prophets. Those who deny this do so, not because its truth is not clear to them, but because of their own sense of superiority. Acknowledging its veracity amounts, as they see it, to accepting the intellectual superiority of the proponent of the Quran. And their jealousy and arrogance do not allow of such an acknowledgement. Instead of accepting the truth, they want to exterminate the dayee himself. However, this is not possible in this world of God. All their plans to censor the dayees’ words will fail, and when God’s scales of justice are put in place, they will see that those actions, which had given them the conviction of securing success and salvation, are quite without value. True argument is one of God’s signs. One who does not bow to a true argument, fails to bow to God. Such dissenters will enter the next world divested of all support.
