Second Argument
of not Wavering by the Holy Prophet, peace be upon him

Surah al-An‘am, 6:58

Without any doubt or ambiguity, I have with me from my Lord manifest Signs of the highest order testifying to my truth and veracity and you have rejected this veracity. You seek to hasten the punishment that is to befall you in consequence of your rejection; but inflicting this punishment is not within my power. The governance of affairs rests with none except Allah, but bear in mind that those who reject will come to suffer. Allah will continue to manifest the truth which I have brought and He (Allah the Exalted) is, without any uncertainty or doubt, the Greatest Judge to decide between falsehood and truth. He will humiliate the liar and grant victory to the truthful.
